fa425b54b7 Don't count duplicate assignments to the same property as distinct ones. 
In the ThisNamedPropertyAssignmentFinder, duplicate assignments to the same
property were counted as distinct assignments.  As a simple fix, subsequent
ones overwrite the previously recorded assignment.

This will reorder the assignments, but it is safe since they are restricted
to have only constants and parameters on the right-hand side (and there are
no assignments to the parameters).

FAST_DOUBLE_ELEMENTS.

8e31371d0e Move logic for hidden properties into the JSObject. 
Previously, the logic using the hidden properties backing object was
spread accross use sites. Now it's all contained in JSObject, with
only simple accessors available.
Also change the backing object to be a StringDictionary rather than a JSObject.
There's still room for improvement by making a hash-table that don't
store property details as well.

b5be9fa83a Fix map modification in transition tree traversal. 
While traversing the transition tree we build a work-list using the map
field of maps. Setting those map values with a write barrier causes
black-to-gray changes on maps which are currently not recognized as
such, hence their computed size might be off.

de7b222e36 Support for precise stepping in functions compiled before debugging was started (step 2) 
This change will ensure that full code with debug break slots is compiled and activated for all functions which already have activation frames.

This additional handling is only for functions which have activations on the stack, and that activation is of the full code compiled without debug break slots. In that case the full code is recompiled with debug break slots. It is ensured that the full code is compiled generating the exact same instructions - except for the additional debug break slots - as before. The return address on the stack is then patched to continue execution in the new code.

Also fixed SortedListBSearch to actually use the passed comparision function.

c1b978c076 Fix a GC-safety issue in optimized code. 
It's not safe to use an immediate heap object in generated unless we take
pains to ensure it's not in new space.  Continue using the caller's context
for inlined functions on all platforms except IA32.

3fabe323f2 Add kHeaderSize constant to SeqString. 
This prevents potential misuse of SeqString::kHeaderSize as in the
case of live byte counting in incremental marking stub. All stubs
picked up the undefined size constant SeqString::kHeaderSize, thus
the computed size of all strings was off by two pointers slots.

Fix aggravating bug on X64 where assembler code used a value that was off
by a factor of 2^31.

Ensure that sweeping clears live-bytes. Added other missing increments.

Added print statements to trace live-byte modifications, under a flag.

cf63503cad Unify the handling of comparinsons against null and undefined. 
Although this patch is not small, most parts of it are rather mechanical:

 * First of all, the concept of a 'nil-like' value is introduced, which can be
   null or undefined. They are treated symmetrically regarding comparisons, so
   it makes sense to handle them in a uniform manner. It is a mystery why
   JavaScript defines two of those beasts, when even *one* is a design wart...

 * Extended and renamed a few things which now handle undefined in addition to
   null.

 * Made the parts of the full code generator and the hydrogen generation which
   deal with comparisons a bit more similar regarding their handling of special
   cases.

 * Refactored the syntactical detection of special cases for comparisons,
   hopefully making them a bit more readable and less copy-n-paste-oriented.
   Things like this should really be a one-liner in any sane programming
   language... :-P

 * Cut down the length of the argument lists of a few functions to something
   less insane, making them more easily understandable locally. This involves
   minor code duplication, but this was a good tradeoff and can be remedied
   later if necessary.

 * Replaced some boolean arguments with more readable enums.

 * Fixed a TODO: Values which are definitely a Smi or unboxed can never be equal
   to null or undefined.

-- use updated xxxCFunction macros.
-- update InstanceOfStub to support crankshaft
DoDeferredLInstanceOfKnownGlobal
-- Provide code-patching and I-cache flushing support for generated
code, used for InstanceOfStub under crankshaft (not submitted here).

The Great Master Plan is to move the recognition of special cases for

equality comparisons involving null is pushed from the parser to the code
generators, removing the need for a special AST node. (There are rumors from
usually well-informed sources that this node type is actually a relic of ancient
crankshaft days...)

The next steps will be the unification of null/undefined handling and pushing
the special case handling in crankshaft even further down the pipeline, enabling
the recognition of cases like "var foo=null; if (foo === bar) ...", but these
will be in separate CLs.

81df4a42e4 Support for precise stepping in functions compiled before debugging was started (step 1) 
This change will ensure that all non-optimized code will be compiled
with debug break slots when debugging is initiated. This is handled by
scanning the heap for non-optimized functions without debug break slots and setting their code to be lazy recomplied. When the lazy recompilation happens the code will ge generated with debug break slots (if debugging is still active at that point in time).

Use the BitField helper class for the code flags, so that we do not have to
define both a shift and a mask explicitly.  This makes changing the flags
layout simpler.

Also, make the 'mask' and 'max' members of BitField into constants, because
they are constant and so that they can be used as constant expressions.
E.g., so they can be used in declaring other const members or in static
asserts.

1341ae7c1a Re-use phi reachability information to avoid a fixed-point computation. 
When we propagate the information that a value is not convertible to integer,
there is no need for a separate fixed-point computation, we can do things the
"Millikin way" (tm), folding as much computation as possible into a single pass:
;-) We already have the phi node reachability information, so we can easily
propagate this while doing the representation histogram computation.

ffb70bc843 Improved phi reachability computation a bit. 
The use-def relation between phis is mainly "forwards" (i.e. from phis with
smaller IDs to ones with larger IDs), so the fixed point computation terminates
faster when iterate through the phis in a "backwards" manner. This is quite
visible in complex Mandreel-generated code, where a few hundred phis with
non-trivial use-def chains are generated.

2c8680cc46 Avoid size increase of snapshot. 
The prototype of builtin functions is already unwritable, so we don't
have to make it so (the default map for functions changes after builtins
are initialized).

We no longer need to make the prototype non-extensible, since all properties
that are ever read by the bultins code has been added and frozen already.
Adding properties to the prototype, or changing its __proto__, cannot affect
code.

Removing these two pieces of initialization code reduces the snapshot size
by a few Kb.

that generate code (function declarations) I inserted a separate

4084e698c3 Fixed a bug in the chaining of fixup position 
The ARM and MIPS assemblers had a bug where they did not handle the last element
in the list of code positions correctly during the fixup of offsets for forward
jumps. This happened when the first instruction contained a forward jump to a
label, and that label was used in a forward jump later, too.

Unified the code for Assembler::next on ARM and MIPS while we were there.

Added test cases, even for ia32/x64, which seem to be correct, even I don't
fully understand why... %-}

9e2db4c0f0 MIPS: Fix KeyedStoreStubCompiler::GenerateStoreFastDoubleElement() 
Test regress-91013.js (to ensure that the stored value was returned) passed on mips
without this fix, since the input value (in value_reg, a0) also happens to be in
mips return value register v0 at the time of call.

But it is fragile to depend on that behavior, so an explicit move from a0 to v0
is warranted. This fix puts that move in the delay slot of the Ret().

a546e4a8dd Fixed bool <-> Executability confusion and improved typing a bit. 
Passing a value of type Executability to a function expecting a bool worked only
by accident (because of the order of values in the enum). But using boolean
parameters is often a bad idea, anyway, so we use Executability directly.

Just another example why implicit type conversions in C++ are a bad idea... :-P

This improves our static type information by calculating the result type

the write barrier in the following example where it was not possible before:

function f(x) {
  var y = x + 1;
  if (y > 0 && y < 100) {
    a[0] = y;
  }

on negative inputs to Math.floor. x64 already uses this instruction.

808748b44d Do not use deprecated ARM instructions in DirectCEntryStub::GenerateCall. 
Non-ancient versions of the ARM-ARM explicitly deprecate most uses of the PC
within instructions and older ARM implementations have a non-predictable offset
(8 or 12) for some of these deprecated uses. Avoiding the deprecated instruction
costs us one additional instruction in DirectCEntryStub::GenerateCall, but this
should not cause any significant performance degradation.

The deoptimizer still uses the PC in a stm instruction, but it is a bit unclear
what to do about that, so simply a comment has been added to reconsider this in
the future.

06bea35f7f Simplify and optimize ToBoolean handling. 
Changing our builtin JavaScript code slightly, we can make sure that we never
see internal objects as arguments for ToBoolean at runtime. Removing that case
from the stub generator and crankshaft makes things a lot easier.

Heap numbers can never be undetectable (only strings and spec objects can), so
we can leave out a useless test.

Try to re-use a non-null register value when returning 'true' in some cases.

Removed special handling of the 'handle all' case, it will very probably never
happen in real code and only makes things more complicated.

Improved naming of the ToBoolean stubs a bit, reflecting the order in which
cases are handled in the code itself.

* Fix performance problem in IA32 and x64. Refine the checks
for minus zero and avoid unnecessary deoptimizations on Math.floor.

b625ce2b6b Fix a bug in scope analysis. 
When recompiling code (e.g., when optimizing) we could incorrectly hoist
some function expressions.  This leads to incorrect results or a crash.  The
root cause was that functions were not correctly categorized as expression
or declaration at parse time.

This requires some extra hoops to prevent the print name "anonymous" for
functions created by 'new Function' from establishing a binding.

bdf6895bb3 Encapsulate element handling into a class keyed on ElementsKind 
Advantage is that it's much easier to add new element types (like FAST_SMI_ELEMENTS), and that handling logic for each element kind is (more) consolidated.

Currently, only GetElementsWithReceiver uses the new encapsulation, but the goal is to move much more element functionality into the class incrementally.

ffa08197e4 tighten invariants of HValue::InferRange 
* src/hydrogen-instructions.cc (HValue::InferRange): Only mark values
  with int32 representation as never being -0.  Always return a non-NULL
  value; callers should check for representation().IsNone() if that's
  their concern.

  In practice these invariants were not violated by callers, but they
  were sometimes two calls away, which seems brittle.

4487f8c050 Revert "Revert "Fix a bug in scope analysis."" 
Reapply r8783 with an additional fix.

Because the preparser and parser do not use the same scope analysis to
determine if a function can be lazily compiled, the parser can have false
positives.  Rather than treating this as a parse error, treat the preparser
as authoritative and eagerly compile the function.

e48ec1c4bd Use type info for the ToBoolean translation in crankshaft. 
To do this, the Branch instruction needs to carry around a temporary register,
but only when the crankshafted code will make a map access. When the
crankshafted code sees an object of a type it hasn't encountered before, it will
always trigger a deopt. Another option in theses cases would be calling a
ToBooleanStub which can handle all types, but then one has to be careful to
*not* trigger a GC (which is currently a bit tricky to achieve).

Const-corrected ToBoolean::Types. Moved the NeedsMap logic into ToBoolean::Types
itself, where it belongs.

This patch improves a lot of benchmarks, crypto-orig even by 16.7%, but slows
down others. The slowdown has to be investigated, but I'd like to get this patch
out first to fix the flakiness problems we currently have due to the previous
crankshafted ToBoolean.

result always fits into a signed int32.

73f8cec70e Do not explicitly record undetectable objects in the ToBoolean stub. 
Loading the map within the stub already implies a check for an undetectable
object, so there is no need to record this separately. Furthermore, this brings
the size of the type info to record down to 8 bits, removing the need to find a
place for the ninth bit in the Code object. ;-)

f7138b1427 Implement a type recording ToBoolean IC. 
The IC records the set of types it has seen, e.g. {String} or {Boolean,
Undefined}, etc.  Note that in theory this could lead to a large number of
different ToBoolean ICs (512, to be exact, because we distinguish 9 types),
but in practice only a small handful of them are actually generated.

Currently the type recording part is only implemented on ia32, other platforms
continue to work like they did before, though.

Removed some dead code on the way.

85f5afb717 Correctly mark functions from our natives files during compilation. 
When creating a CompilationInfo we always have the script and can
determine if it is a natives script.

Now that all natives functions are recognized as such, many of them
are called with undefined as the receiver. We have to use different
filtering for builtins functions when printing stack traces.

Also, fixed one call of CALL_NON_FUNCTION to be correctly marked as a
method call (with fixed receiver). Now that CALL_NON_FUNCTION is
marked as a native function this caused the receiver to be undefined.

6098abf46e Fix the debugger for strict-mode functions. 
undefined is passed unchanged as the receiver for strict-mode
functions through call and apply. Also, if a strict-mode function is
called without an explicit receiver, undefined is passed as the
receiver (not the global object as for other functions).

C++'s 'great' idea of implicitly converting an enum to an integral value hit us

relocation table. Encapsulated the AST ID recording a bit, which helped a lot to

615add8463 Expose APIs for detecting boxed primitives, native errors and Math. 
While implementing structured clone I found that I need support
for detecting and creating objects using the builtin Number, String
and Boolean constructors; this CL adds this support. I also need
to be able to detect entities of "native object type (e.g., Error)",
hence the new IsNativeError() calls.

dbf0aee6ae simplification to HClampToUint8 
* src/hydrogen-instructions.h (HClampToUint8): Don't mark as having
  flexible representation; instead the output is always an Integer32.
  There is no input representation restriction, so we can still perform
  input-specific truncation.

I tested by looking at the --print-code of

var a = PixelArray(1000000)
function fill(a,x) { for (var i=0; i<a.len; i++) a[i] = x; }

Seems to optimize fine both for double and integer inputs.  But perhaps
there is a better test, for which the original code does better, and
this is a bogus patch.

620d50af55 Avoid patching code after the call to binary operation stub in optimized code 
This patch just adds a nop after the call to the binary operation stub in optimized code to avoid the patching for the inlined smi case used in the full code generator to kick in if the next instruction generated by the lithium code generator should accidentially enable that. For calls generated by CallCodeGeneric this was already handled on Intel platforms, but missing on ARM.

On IA-32 I did also try to check for whether the code containing the call was optimized (patch below), but that caused regressions on some benchmarks.

890bc1607a Fix a potential crash in const declaration. 
Declaration of const lookup slots would trigger an assertion if there was a
setter somewhere in the prototype chain, and that setter was shadowed by a
non-readonly data property also in the prototype chain.

c71cf782e8 Drastically reduce the transitive dependencies of jsregexp.h, making it (almost) 
architecture-independent.

jsregexp.h is itself included transitively quite a lot, and by getting rid of 19
of its dependencies (which even included things like src/cpu.h, the various
assemblers, etc.), the recompilation behaviour is a bit less funny than it was.

5528ce7057 MIPS: Cleaned up calling-related methods in the assembler. 
Patterned after r8482, Cleaned up calling-related methods in the ARM assembler.

On MIPS I completely refactored the Jump and Call methods.
All the Jump and Call macro helpers have been replaced with overloaded functions
(matching the ARM version) and using default parameter values where possible.
The previously mostly-unused CallSize function is utilized as well (same as on ARM).
The unused Jump(Operand, ...) and Call(Operand, ...) versions have been completely removed.
I also removed the Jump(BranchDelaySlot, ...) and Call(BranchDelaySlot,...) methods as
they were unused and declaring them would either result in a lot of unused code or the
previously experienced macro-hell. The only exception to this is for Ret() where the
branch delay slot is often used.

This fixes the failing debug tests for example cctest test-debug/DebugStepFor.

4145dded9a MIPS: port Introduce code flushing of RegExp code. 
Ported r8532 (c9db503)

Original commit message:
Due to issues relating mostly to chrome extensions we have lately been
running into OOMs that are caused by our executable space running
out. This change introduces flushing of code from regexps if we have
not used the code for 5 mark sweeps.
The approach is different from the normal function code flusing. Here
we make a copy of the code inside the data array, and exchange the
original code with a smi determined by the sweep_generation (a new
heap variable increased everytime we do mark sweep/compact). If we
encounter a smi in EnsureCompiled we simply reinstate the code
object. If, in the marking phase of mark sweep, we find a regexp that
already have a smi in the code field, and this is more than 5
generations old we flush the code from the saved index.

10bb16f495 Add support for lazy deoptimization from deferred stack checks 
The debugger can be entered from the deferred stack check in optimized code. This can cause both lazy deoptimization and debugger deoptimization (setting the first break point and inspecting the stack for optimized code respectively). This required deoptimization support from the deferred stack check.

The lazy deoptimiztion call is inserted when the deferred code is done including restoring the registers. The bailout to the full code is the begining of the loop body as that is where the stack check is sitting in the optimized code. The bailout is not to the stack check in the full code as that is sitting at the end of the loop.

0f682143d9 Introduce code flushing of RegExp code. 
Due to issues relating mostly to chrome extensions we have lately been
running into OOMs that are caused by our executable space running
out. This change introduces flushing of code from regexps if we have
not used the code for 5 mark sweeps.

The approach is different from the normal function code flusing. Here
we make a copy of the code inside the data array, and exchange the
original code with a smi determined by the sweep_generation (a new
heap variable increased everytime we do mark sweep/compact). If we
encounter a smi in EnsureCompiled we simply reinstate the code
object. If, in the marking phase of mark sweep, we find a regexp that
already have a smi in the code field, and this is more than 5
generations old we flush the code from the saved index.

f3d1453f83 As part of allowing different contexts for inlined functions, eliminate most explicit reads of the context from the stack frame in ia32 crankshaft codegen. 
Eliminates the enum flag RESTORE_CONTEXT and CONTEXT_ADJUSTED, and adds a context HValue and LOperand to many hydrogen and lithium instructions.

Context is still used from the stack from in CallKnownFunction (this seems safe), and in CallRuntimeFromDeferred in lithium-codegen-ia32.cc, which needs to be fixed.

c5aebcb7b0 MIPS: port Introduce scopes to keep track of catch blocks at compile time. 
Port r8496 (b7d5ecf0).

Original commit message:
Introduce scopes to keep track of catch blocks at compile time.
The catch variable is bound in the catch scope. For simplicity in this
initial implementation, it is always allocated even if unused and always
allocated to a catch context even if it doesn't escape. The presence of
catch is no longer treated as a with.
In this change, care must be taken to distinguish between the scope where a
var declaration is hoisted to and the scope where the initialization occurs.

Ported 8452 (8a2a360)

Original commit message:
Before: every context cached the nearest enclosing function context. This
assumed that for nested contexts (i.e., with and catch contexts) the
enclosing function had a materialized link in the context chain.
Now: when necessary, we loop up the context chain to find such a context.
This enables catch contexts without forcing the enclosing function to
allocate its own context.

90c9f1b989 Suspend runtime profiler as soon as we exit JS. 
Lots of web pages have really frequently firing timers that keep the
profiler thread spinning if we require a period of JS inactivity
before suspending the profiler. While it's possible to throttle it by
increasing the sleep delay and adjusting the duration of the required
inactive period, it seemed much simpler to just stop it immediately on
exiting JS.

Stopping the profiler this way effectively turned off two optimization
heuristics: 1) eager optimization (it's reset on waking up the
profiler and now the profiler wakes up much more frequently) and 2)
optimization throttling based on JS to non-JS state ratio (the ratio
is now 100%). I removed these two heuristics and found no performance
regressions so far.

7d2be7c0e0 Support debugger inspection of locals in optimized frames 
Optimized frames are now handled by the debugger. When discovering optimized frames during stack inspection in the debugger they are "deoptimized" using the normal deoptimization code and the deoptimizer output information is used to provide frame information to the debugger.

Before this change the debugger reported each optimized frame as one frame no matter the number of inlined functuions that might have been called inside of it. Also all locals where reported as undefined. Locals can still be reposted as undefined when their value is not "known" by the optimized frame.

As the structures used to calculate the output frames when deoptimizing are not GC safe the information for the debugger is copied to another structure (DeoptimizedFrameInfo) which is registered with the global deoptimizer data and processed during GC.

54d6072332 Change the handling of stack check on backward branches 
The hydrogen stack check instruction is now added to each loop and the stack check handling on the back edge has been removed.

This change causes regression on small tight loops as the stack check is now at the top of the loop instead of at the bottom, and that requires one additional unconditional jump per loop iteration. However the reason for this change is to avoid worse regressions for upcoming changes to correctly support debugger break in optimized code.

Fixed regex for matching styles in date and number format.

intermediate cleanup step to add type recording at the call site.

Note that the MIPS implementation has not really been touched, so it should
continue to work, too.

The bug was exposed with the Arm & Mips fix in r8321, "Fix wrong
parenthesis in stub ARM and MIPS generation code."

af24067fa5 Refactor the way we collect the information for associating type-related infos 
with AST IDs. Previously 3 different places had to match in how they handle a
given case, now we are down to 2, with an even simpler logic.

The downside is that due to this simpler logic the allocated dictionary could be
larger than before, but test have shown that this happens *very* rarely, because
its capacity is rounded to the next power of 2, anyway. Furthermore, the oracle
doesn't live long enough that we should really care.

The whole oracle is probably still a bit too tricky in its details, but this is
at least a step into the right direction.

8c538d9012 Made parser not accept unicode escapes inside "native" when used as a keyword. 
This is a regression relative to the original behavior, when "native" was a keyword,
since keywords cannot contain esacpes.

Added tests for escapes and for not allowing line-terminators betwen "native" and "function".

480ec43c4e Make "native" not a keyword. 
We now only recognize "native function" when it occurs in extension scripts
(parsing with a non-NULL extension), and only if there is no line-terminator
between "native" and "function" (so that it would otherwise be a Syntax Error).
Preparsing never recognizes native functions, which is acceptable since we
never preparse extension scripts (because we don't allow lazy functions
anyway).

7d527f857f Change the representation of catch contexts. 
Before, they had no extra slots and an extension object with one named
property.  Now, they use the extension slot for the property name and have
an extra slot for the thrown object.  This increases the size of the context
itself, but removes overall allocation and eliminates a level of indirection.

a4cf7be941 First steps towards better code generation for LBranch: 
* AST Expression nodes get a separate testing ID to record type info in
   ToBooleanStub later. This is necessary to avoid clashes with other uses of
   already existing IDs.

 * In order to avoid threading the condition expression through tons of places,
   TestContexts carry it now with them. Note that we will probably only need the
   testing ID of the expression, but having the whole thing at hand makes
   debugging easier. Probably we will change this later...

5a236ce6fd Add support for hydrogen control instructions with >2 successor blocks. 
This change makes the number of successors of a control instruction
configurable with a template parameter and changes the existing instructions
to use it.

To iterate over all successors I added an iterator instead of always calling
First- and SecondSuccessor.

508b22c436 "Deiceolate" Thread classes. 
Thread class was receiving an isolate parameter by default.
This approact violates the assumption that only VM threads
can have an associated isolate, and can lead to troubles,
because accessing the same isolate from different threads
leads to race conditions.

This was found by investigating mysterious failures of the
CPU profiler layout test on Linux Chromium. As almost all
threads were associated with some isolate, the sampler was
trying to sample them.

As a side effect, we have also fixed the DebuggerAgent test.

Thanks to Vitaly for help in fixing isolates handling!

5872e8ee2f Refactor storage of global handles. 
We used to have a linked list of nodes that were internally
block-allocated.

I kept the node blocks and put them on two lists: 1) the list of all
allocated blocks, 2) the list of blocks with used nodes. (1) is used
to reclaim blocks and (2) is used for traversal during GC. To make
traversal on scavenges faster the nodes holding new space objects are
grouped in an auxiliary array.

This changes the minimal memory usage from 5 words per global handle
to 4. Additional word is used for new space handles.

Only do so if the estimated number of elements is low compared to the
end position for the slice. This is similar to other heuristics used
for array operations that use the %GetElementKeys runtime function.

The Advance() function of the class responsible for iterating
environment uses didn't always advance as far as it could (relying on
the HasNext predicate to finish advancing).  This is brittle.

The HasNext predicate also didn't advance as far as it could when it

0163b443d2 MIPS: port Implement set trap for proxies, and revamp class hierarchy in preparation 
Ported commits: r8126 (6461bae)

Original commit message:
- Introduce a class JSReceiver, that is a common superclass of JSObject and
JSProxy. Use JSReceiver where appropriate (probably lots of places that we
still have to migrate, but we will find those later with proxy test suite).
- Move appropriate methods to JSReceiver class (SetProperty,
GetPropertyAttribute, Get/SetPrototype, Lookup, and so on).
- Introduce new JSFunctionProxy subclass of JSProxy. Currently only a stub.
- Overhaul enum InstanceType:
* Introduce FIRST/LAST_SPEC_OBJECT_TYPE that ranges over all types that
represent JS objects, and use that consistently to check language types.
* Rename FIRST/LAST_JS_OBJECT_TYPE and FIRST/LAST_FUNCTION_CLASS_TYPE
to FIRST/LAST_[NON]CALLABLE_SPEC_OBJECT_TYPE for clarity.
* Eliminate the overlap over JS_REGEXP_TYPE.
* Also replace FIRST_JS_OBJECT with FIRST_JS_RECEIVER, but only use it where
we exclusively talk about the internal representation type.
* Insert JS_PROXY and JS_FUNCTION_PROXY in the appropriate places.
- Fix all checks concerning classification, especially for functions, to
use the CALLABLE_SPEC_OBJECT range (that includes funciton proxies).
- Handle proxies in SetProperty (that was the easiest part :) ).
- A few simple test cases.

0aa422923c Eagerly deoptimize on never-executed code-paths. 
If type-feedback indicates that an expression was never executed in
the non-optimized code, we insert a forced deoptimization right away
to enable re-optimization if we ever hit this path.

With this change we still continue to build the graph. As a next step, we
should remove the dead code after the deoptimize.

I had to remove one assert about the optimization status in a test since
we now immediately deoptimize after exiting the loop that triggers OSR.

Also remove a restriction that control-flow from an inlined function in a
test context always reaches both true- and false-target.

Now the signed comparison condition codes are always used with CompareObjectType. The type is only a byte and ldrb will do sign extension, so signed and unsigned comparison will give the same result. Signed condition codes are easier to read.

ab00b00a87 Removed all references to v8/src from i18n extension code. 
Removed I18N enum from v8/src/natives.h

Removed use of Vector and natives.h from i18n-extension.cc. Added new
python script that generates i18n-js.cc from i18n.js.

Made all paths absolute pointing to either v8/include or
v8/src/extensions/experimental.

Exported -Iv8 for embedders (-Iv8/include was there already).

670f947a5c Implement set trap for proxies, and revamp class hierarchy in preparation: 
- Introduce a class JSReceiver, that is a common superclass of JSObject and
  JSProxy. Use JSReceiver where appropriate (probably lots of places that we
  still have to migrate, but we will find those later with proxy test suite).

- Move appropriate methods to JSReceiver class (SetProperty,
  GetPropertyAttribute, Get/SetPrototype, Lookup, and so on).

- Introduce new JSFunctionProxy subclass of JSProxy. Currently only a stub.

- Overhaul enum InstanceType:
  * Introduce FIRST/LAST_SPEC_OBJECT_TYPE that ranges over all types that
    represent JS objects, and use that consistently to check language types.
  * Rename FIRST/LAST_JS_OBJECT_TYPE and FIRST/LAST_FUNCTION_CLASS_TYPE
    to FIRST/LAST_[NON]CALLABLE_SPEC_OBJECT_TYPE for clarity.
  * Eliminate the overlap over JS_REGEXP_TYPE.
  * Also replace FIRST_JS_OBJECT with FIRST_JS_RECEIVER, but only use it where
    we exclusively talk about the internal representation type.
  * Insert JS_PROXY and JS_FUNCTION_PROXY in the appropriate places.

- Fix all checks concerning classification, especially for functions, to
  use the CALLABLE_SPEC_OBJECT range (that includes funciton proxies).

- Handle proxies in SetProperty (that was the easiest part :) ).

- A few simple test cases.

6453056bb6 Reduced the code ping-pong between the full code generator and contexts a bit. 
* Centralized AND/OR handling, keeping related code together.

* Removed HandleExpression/HandleInNonTestContext and introduced VisitInSameContext instead, making it more obvious what's actually going on.

* Consistently use a new context when visiting the left sub-expression of an AND/OR. Note that the context stacks in the full code generator and crankshaft are still a bit out of sync for the right sub-expression.

c5fc4b9099 Add asserts and state tracking to ensure that we do not call 
into C++ without having a valid stack frame that can be
traversed at GC.
Also add asserts to track that we do not try to generate a stub
while we are generating a stub, since the stub creation code is
not GC safe.

dcb558fdf0 Push the general AST id field down from ASTNode to Expression. 
Almost all uses were below Expression already, only a single use in IfStatement
had to be handled explicitly (probably an oversight from earlier changes?). This
is a small step towards a less ad-hoc handling of IDs in the front end.
