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.

3f8a191725 Double allocation size for special json strings on every resize (fixes 
crbug 83877)

The issue was that with the relatively small start and increment size of the string we created a ton of string handles when scanning a large string with special characters (500k+ in this case).

In addition, since we can not be sure the the newly allocated string
is in newspace a check is introduced and if not a filler object is
inserted instead of shrinking.

64c610727d MIPS: Added the stop() instruction with same behavior as on Arm simulator. 
The already working watchpoint break mechanism has been extended to handle "stop" instructions, with text messages.

Explanation (also in constants-mips.h):
On MIPS Simulator breakpoints can have different codes:
- Breaks between 0 and kMaxWatchpointCode are treated as simple watchpoints, the simulator will run through them and print the registers.
- Breaks between kMaxWatchpointCode and kMaxStopCode are treated as stop() instructions (see Assembler::stop()).
- Breaks larger than kMaxStopCode are simple breaks, dropping you into the debugger.

The current values are 31 for kMaxWatchpointCode and 127 for kMaxStopCode.
From the user's point of view this works the same way as the ARM stop instruction except for the break code usage detailed above.

b92ef0be32 MIPS: port Fix calls of strict mode function with an implicit receiver. 
Port of r8040 to mips.

Original commit message:
Strict mode functions are to get 'undefined' as the receiver when
called with an implicit receiver. Modes are bad! It forces us to have
checks on all function calls.
This change attempts to limit the cost by passing information about
whether or not a call is with an implicit or explicit receiver in ecx
as part of the calling convention. The cost is setting ecx on all
calls and checking ecx on entry to strict mode functions.
Implicit/explicit receiver state has to be maintained by ICs. Various
stubs have to not clobber ecx or save and restore it.
CallFunction stub needs to check if the receiver is implicit when it
doesn't know from the context.

6f775f2fb0 Fix calls of strict mode function with an implicit receiver. 
Only IA32 version for now. I'll start porting.

Strict mode functions are to get 'undefined' as the receiver when
called with an implicit receiver. Modes are bad! It forces us to have
checks on all function calls.

This change attempts to limit the cost by passing information about
whether or not a call is with an implicit or explicit receiver in ecx
as part of the calling convention. The cost is setting ecx on all
calls and checking ecx on entry to strict mode functions.

Implicit/explicit receiver state has to be maintained by ICs. Various
stubs have to not clobber ecx or save and restore it.

CallFunction stub needs to check if the receiver is implicit when it
doesn't know from the context.

3c7e1d7015 Create stand-alone json parser (including scanner). 
The current json parser and scanner inherits fromt he normal scanners and parsers,
which are more complicated than we need for parsing json.

The supplied scanner works directly on the string supplied and has a
fast case mode for scanning only ascii characters (it will simply
create a substring or a symbol directly from the existing string). To
allow for creating symbols from a substring I have added a
SubStringAsciiSymbolKey that creates the hash based from our string
without extracting the sub-string. In case we need to add the symbol
it simply creates the symbol directly from the characters inside the
given string.

a1bcafab69 Improve bit tests on IA32. 
Bit tests with a memory operand should be avoided on Intel processors.
On Atom bts with a memory operand has 10~11 cycles latency and on Core 2
it has 5~6 cycles latency, and also produces multiple uops.
If the bit base operand is a register the latency is 1 cycle instead.
This CL improves several cases from Kraken 1.1 benchmark on Atom. For example,
12% for imaging-desaturate, 8% for audio-fft, and 5% for audio-beat-detection.

f2cb08f1c2 Fix handling of -0 in the unary-op IC and avoid repeated patching/transitions. 
When the stub return a heap number we do a state transition to
a version HEAP_NUMBER that can handle -0.

There is room for further improvement in the typefeedback for the
case of -0. This change however does not address this and only fixes
the acute issue.

123500999f Reland 7917: 
Better support for 'polymorphic' JS and external arrays

Allow  keyed store/load stubs to switch between external array and fast JS arrays without forcing a state transition to the generic stub.

There CL consists of two pieces of functionality. First, code stubs for fast element arrays don't immediately transition to the MEGAMORPHIC state when there's a map mismatch. Second, two ICs are cached per map for fast elements, the MONOMORPHIC version, and a new MEGAMORPHIC version that handles two or more different maps and dispatches to shared stubs to perform the array operation.

f39b0dfccb Handle all kind of arguments in the ToBooleanStub. While this is not very thrilling in itself, it is one of several steps to add type recording to this stub. Removed a duplicate check for null in the ARM stub and made a tiny simplification, removing a sub instruction. 
As a side note, this change has some positive impact on the performace, e.g. imaging-darkroom is 8.3% faster and ws-ieee754conv is even 19.9% faster. No idea why the speedup is so big in some cases, but never look a gift horse in the mouth... ;-)

e14402b1df A first skeleton for introducing Harmony proxies. 
1) Add new type JSProxy for representing proxy objects.
   Currently devoid of functionality, i.e., all properties are undefined.

2) Some rudimentary global $Proxy functions to create proxies.

Next step: Hook up getProperty and getOwnProperty handlers. Will probably
require introducing a new LookupResult type, which is a mixture of
INTERCEPTOR (handles any property) and CALLBACK (calls back to JS).
Can we unify this somehow?

TODO: Should probably rename existing Proxy type to something like
"Foreign", to avoid confusion.

5f29f9bd8e Don't use environment values at certain deoptimize-instructions. 
If a HDeoptimize does not cut away parts of the control-flow-graph
we don't need to insert uses to correctly elimiate dead phis since
the full function is visible to the optimizing compiler.

This is a small improvement of the change r7221 which fixed a problem
when deoptimizing on never executed case-clauses.

4e18d50834 Add constant splitting for user controlled constants in the full compiler 
This is IA32 only for now.

Added a random value to each assembler instance (JIT cookie) to be used for constant splitting. Added safe versions of setting a register with an immediate value and for pushing an immediate value. Used these functions where user controlled immediate values could be emitted in the code stream. I also used it for immediates which are an argument number even though the number of formal arguments is currently limited to 16k.

I found no compares directly with user controlled constants.

I am not sure whether the test is that useful, but it might catch some changes missing constant splitting.

4912c0371b A few "extract method" refactorings, trying to get individual method definitions 
onto a sinlge 30" screen. A lot of times, the AST visitor stops a bit too early,
so we have to do the rest of the dispatch by hand. This is caused by the fact
that the kind of the AST nodes are a bit too coarse for some traversals (e.g. a
single node type for all binary ops), perhaps one could try to refine this a
little bit more.

5b2e2636b7 Faster string equals in generated code. 
In my previous change I mixed up "compare" and "equals". This made us
miss the fast length check before comparing strings for equality.

Now we have a separate helper for "equals". It shares some of the
inner loop details with "compare". I'll see if this can be cleaned up
without making it unreadable.

3e94ac952d Change heuristics for deciding phi-representation types to use int32 more frequently. 
Until now we conservatively chose a double representation if
at least one use occurs in a double operation. This causes performance
degradation in many cases where there are mixes uses (integer and double)

e.g.:

for (int i = 0; i < 10; i++) {
  var t = i / 3.5;
  a[i] = t;
}

where the use in i/3 requires a double, where as the keyed store requires i
as an integer.

For these cases we want to have i as an integer and convert it only before the
double division.

In order to avoid unconditional deoptimization in some rare cases, we check
phis if there is any conversion that will always fail when converting a
heap-number constant to int32.

01707c7106 ARM: Changed the handling of compiletime CPU feature detection 
Always use CpuFeaturesImpliedByCompiler() when selecting CPU features. This checks both for CAN_USE_ARMV7_INSTRUCTIONS and CAN_USE_VFP_INSTRUCTIONS and for GCC preprocessor symbols. This will support using the CAN_USE_XXX for a simulator build used for generating a snapshot followed by a crosscompile using -march= and -mfpu= for selecting the (minimal) target device CPU features. The snapshot will use instructions based on the CAN_USE_XXX whereas the target will at least use features based on both CAN_USE_XXX and -march= and -mfpu=, but will try runtime CPU feature detection a well looking for somethis better.

Remove the compiler based CPU feature detection from the OS::CpuFeaturesImpliedByPlatform() as it did not belong there. Also was already in the CpuFeaturesImpliedByCompiler().

Add the variable 'v8_can_use_vfp_instructions' to the GYP file which can be used to turn on CAN_USE_VFP_INSTRUCTIONS when building V8. I did not add any -mfpu= cflags for this, as there are several options here (e.g. vfp and neon).

- It was calculating start_block and end_block incorrectly.

- It was not considering the case when end_block is a loop header itself when searching for the header of the outermost loop.

These bugs do not affect correctness of the allocation but can severely degrade it's quality (cause spills in loop bodies).

a9ea3f98b0 ll_prof: Reduce profiling hooks overhead from >400% to 25%. 
Switched to using binary low-level log instead of the textual log used
by the ticks processor. The binary log contains code-related events,
code object names, and their bodies. When writing to the log we ask
glibc to use a larger buffer. To avoid complex processing of the
snapshot log (which is still textual) the serializer emits final
snapshot position to code name mappings that can be quickly be read
without replaying the snapshot log. (This might be useful for the
ticks processor.)

ec58c05f4e Add support for startup data (snapshot) compression. 
This is for mobile platforms where application footprint size is
important. To avoid including compression libraries into V8, we assume
that the host machine have them (true for Linux), and rely on embedder
to provide decompressed data.

Currently, only snapshot data can be comressed. It is also possible to
compress libraries sources, but it is more involved and will be
addressed in another CL.

00bc2db28f ARM: Support hardfloat in SCons build and make it a build time setting 
Add option armeabi to the SCons build for selecting the floating point variant to use. Also add externally defined CCFLAGS environment for all targets. Run test.py with option -S armeabi=hardfloat to test with hardfloat enabled.

Make selecting hardfloat EABI variant a build-time option instead of a runtime option.

Add a simple check of the EABI variant during V8 initialization to exit if the compilation was not configured correctly. The reason for this is that GCC does not provide a compile time symbol defining the EABI variant. This check is not fool-proof as it cannot check the compilation configuration used for the snapshot if any.

4d1b2b1d38 Change the Hydrogen representation of uses. 
Rather than representing a use as a pointer to an HValue and then searching
for the specific (ambiguous) operand, we now represent a use as a pair of an
HValue and the input operand index.  Additionally, use a linked list instead
of a growable array list since we never use random access.

This allows us to remove a bunch of similarly named and subtly different
functions from the HValue API.  The cost in extra zone allocation per use is
partially offset by reusing use list nodes when replacing a use of one value
with another.

not specifying use-at-start prevents the allocator from using
a register even if there is one available. That's why use-at-start
is required and guarded by assertion)

a932441a0c Cleanup of ScannerConstants, now named UnicodeCache. 
The ScannerConstants class was originally static fields on the scanner class.
During creation of the stand-alone preparser and later isolates, it has been
moved into a separate class with a per-isolate instance.
It is used to hold caching unicode Predicate values.

This change renames the class to UnicodeCache, and passes a reference
to the instance down to methods that doesn't have an easy access to
an isolate (to avoid, e.g., having to do an Isolate::Current() for every
number parsed).

When the TypeRecordingBinaryOpStub expect smi values as input, they might

as holding values that are valid smi values, and will not change the expectations.
However, the stub didn't handle HeapNumbers and always tried to transition again.

Correctly process failures which can be returned by Object::GetProperty
when performing GetRealNamedProperty* queries.

Callback properties can produce exceptions so we need to wrap access to them
into exception checks.  However, despite of many other methods with exception
checks, property access doesn't mandatroy go via JavaScript and hence we
need to inject code to propagate exception to public API TryCatch handlers.

302037d44e Make object groups and implicit references a bit more lightweight. 
We can only call malloc/free once per group and we can avoid scanning
through a list of NULLs if we keep unprocessed groups in the beginning.

I also changed the internal representation of implicit references to
hold a handle to the parent (instead of a direct pointer). The
prologue callback must not trigger a GC, but it's better to be safe.

c9904976f9 Simplify isolates access during stack iteration (WAS: Move SafeStackFrameIterator::active_count_...) 
While trying to fix Mac and Windows versions for this change:
http://codereview.chromium.org/6771047/, I figured out, that we
already store an isolate in StackFrameIterator, so we can use it in
frame objects, instead of requiring it from caller.

I've changed iterators usage to the following scheme: whenever a
caller maintains an isolate pointer, it just passes it to stack
iterator, and no more worries about passing it to frame content
accessors.  If a caller uses current isolate, it can omit passing it
to iterator, in this case, an iterator will use the current isolate,
too.

There was a special case with LiveEdit, which creates
detached copies of frame objects.

ea8312ba33 Reapply: Never use classic code generator. 
Crankshaft is now the default on all platforms. This is the first
patch on the way to removing the classic code generator from the
system.

This time with no removal of the crankshaft flag. --nocrankshaft is
not at all the same as --always-full-compiler which I had used instead
for testing. That was what caused timeouts on the buildbots because of
repeated attempts to optimize hot functions. It makes sense to keep
the crankshaft flag in case you want to run only with the full
compiler and with no adaptive compilation.

2531480d10 Re-establish mips basic infrastructure. 
This commit adds current working versions of assembler, macro-assembler,
disassembler, and simulator.

All other mips arch files are replaced with stubbed-out versions that
will build.

Arch independent files are updated as needed to support building and
running mips.

The only test is cctest/test-assembler-mips, and this passes on the
simulator and on mips hardware.

67f20c4d95 Set optimizable to false on code object if shared function info says so. 
Because we might throw away code when doing code flushing we need to
set the optimizable flag to false in CompileLaze if this has been set
on the shared function info. This is the only place where this can
happen, since we always exchange the code with the laze compile stub
when doing code flushing.

The comment in AbortAndDisable actually states that this is already
the case (and that comment should now be ok).

This patch adds common infrastructure for fast TLS support and
implementation on win32. More implementations will be added soon.

Fast TLS is controlled by V8_FAST_TLS define which is enabled by
default in our gyp and scons builds. The scons build has
fasttls={on,off} option so that we can see the effects of slow TLS
when needed.

3925045f70 Don't rely on C++ object padding across platforms 
The use of sizeof on FrameDescription to get to the additional allocated memory for the frame content relies on the padding of the FrameDescription. On IA32 Linux the FrameDescription is not padded but on ARM Linux it is padded to become 8 byte aligned. With a snapshot generated with the ARM simulator on IA32 Linux that contains one or more of the deoptimization tables the deoptimization did not work as the access to the frame content was one off between the C++ code and the generated code.

cdf65ca087 Reimplement the padding of relocation information for lazy deoptimization on ia32. 
The previous implementation attempted to keep track of the needed
relocation size for deoptimization while generating the optimized
code. That was error prone. This patch moves the relocation resizing
to the deoptimizer as the last step of creating an optimized code
object.

The down side to this approach is that two relocation information byte
arrays are created for all optimized functions that do not have enough
relocation space for lazy deoptimization.

This change adds a new IR instruction for polymorphic loads. It performs
map compares and loads in one IR instruction instead of splitting each

The advantage is a smaller IR and less basic blocks, plus it allows to

a224db3a50 X64: Optimize access to external references. 
Access to an ExternalReference in non-serializable code will try to use
an offset relative to the root-array register.
Since the root-array is in the Heap object, and the Heap object is in
the Isolate object, there's a good chance that any external data field
is within a 32-bit offset of the root array register.
It falls back on the original behavior if the serializer is enabled,
if the root register isn't initialized or if the offset is not representable
as a 32-bit value.

Only for ia32 at this point. If this looks OK to you I will port it.

8066271fd2 Optimize calls to object literal properties that are initialized with a function literal. 
This allows fast calls and inlining of functions like:

var o = {f: function() { return "foo"; }}
o.f();


Object literals that contain function literals are initially created a dictionary mode
object and only transformed to fast properties once all properties are computed and
added. This allows us to create constant function properties for functions declared
inside the object literal. Function literals inside object literals are marked for
pretenuring so that they work as contant function properties.

Object literals without functions should just function as before.

e820926108 Improve ARM-Simulator. 
This patch
- removes the unimplemented code crash when rendering invalid/unknown instructions and prints "unknown" instead.
- prints the beginning of the constant pool marker.
- adds "da" as a shortcut for "disasm".
- print hexadecimal representation of double and single registers. This makes it easier to debug move/conversion code that uses temporary int32 values in floating point registers.
- annotates the stack with short prints of the values (HeapObjects and smis),
- makes disasm take an address or a register as second argument without a third argument, which defaults to printing ten instructions.

c6e37c5dfb Make Script.prototype.nameOrSourceURL use indexOf search first before trying to match with a RegExp. 
This should use Boyer-Moore search with a long string, which is potentially
faster than RegExp search.
The target string is typically, but not guaranteed, at the end of the
source, so for long sources, there will be a lot of characters to skip.

4722f692e4 Make exception thrown via v8 public API propagate to v8::TryCatch as JS thrown exceptions do. 
Correctly process failures which can be returned by Object::GetProperty
when performing GetRealNamedProperty* queries.

Callback properties can produce exceptions so we need to wrap access to them
into exception checks.  However, despite of many other methods with exception
checks, property access doesn't mandatroy go via JavaScript and hence we
need to inject code to propagate exception to public API TryCatch handlers.

fa9e57e326 Change __defineGetter__ and __defineSetter__ to respect non-configurable. 
This makes us compatible with firefox. Earlier on we were somehow
compatible with safari - which will allow defining a getter even when
an existing getter is present and non-configurable. We would, however,
in addition to overwriting the getter also change configurable to
true. The approach used by firefox seems much more sound, i.e., why
should it be possible to use __defineGetter__ or __defineSetter__ to
overwrite a non-configurable getter or setter respectively.

I will file a bug on the webkit bugtracker.

d31594feae Refactor construction of switch statements to avoid subgraphs. 
Refactor construction of switch statements so it doesn't use class
HSubgraph.

There are also a few improvements.  We do not use an auxiliary list of
comparisons because they're embedded as a linked list in the graph
under construction.  We share a common break block for all breaks from
the same switch.  We do not insert empty blocks unless necessary to
maintain edge-split form.

There is also a bug fix.  The entry to a clause body is a potential
join and must have a join ID set, otherwise deoptimization within the
body can go to an unpredictable place in the unoptimized code.

redundant state out of the builder and deferring to the current function's
state.

4707d7ac08 Stop using plain Arrays internally in built-in functions. 
In built-in code we use arrays for internal computations.
This makes it possible to affect the built-in code by putting getters
or setters on the Array prototype chain.
This adds a new internal Array constructor that creates Arrays with
a very simplistic prototype chain that doesn't include any publicly
visible objects. These Arrays shoudl ofcourse never leak outside the
builtins, since that would expose the prototype object.
The prototype object contains only the array functions that we use:
push, pop and join (and not even a toString, so it doesn't stringify
well).

Also change uses of .call to %_CallFunction.

SetElement can cause an exception to be thrown. If its return value
isn't checked, this exception might not be handled at the correct time.
In some cases, it's a matter of returning Exception::Failure() from
a runtime function.
In other cases, code using SetElement on a JSArray has been changed
to setting directly on a FixedArray and only creating the JSArray
at the end.

Do not use subgraphs to implement the translation of simple branching
control flow, for the function body entry, or for labeled blocks.

Combine all the loop construction functions into a single one.

Resolve a possible problem with duplicate AST IDs used both for joined loop
break blocks, the normal loop exit, and for their common successor, by never
introducing the extra (successor) block and instead making the normal loop
exit a predecessor of the break join block.  There is a similar issue with
joined continue blocks.

Remove a (never needed) two-element zone list per each time we replace one
hydrogen value with another.

5a9c4aad23 Make the materialization of smi constants consistent between the two compilers. 
This change makes the full code generator always materialize smi constants to match the behavior
 of the environment tracked in the optimizing compiler. The mismatch between environment
and what the non-optimized code causes problems and potentially crashes when doing deoptimization
and OSR.

6b1530ea6d Fix a stack height mismatch when deoptimizing. 
When deoptimizing from the key subexpression of a keyed arguments access,
the unoptimized code expects to find the value of the receiver on the
expression stack.  The environment of the optimizing compiler did not
contain this value during evaluation of the key subexpression.

735dc96461 Fix bug 73940. 
I think this actually turns the code in question into dead code, because the current definition of UseSparseVariant only allows arrays in DictionaryMode, and these never return encoded ranges from %GetArrayKeys. This is a subtle link between the definition of %GetArrayKeys and UseSparseVariant, so I would prefer to keep the code rather than having an invisible depeendency.

77fffe2207 X64: Implement DoComputeOsrOutputFrame and fix Generate_OnStackReplacement. 
The existing version does not have a correct implementation of
Generate_OnStackReplacement since we do not correctly find the loop
depth. This is mainly because EmitStackCheck in full-codegen-x64.cc
did not write it and partly due to us reading at the wrong offset
(which had no effect when it was not written in the first place, we
simply got a random number from the next instruction).

The DoComputeOsrOoutputFrame is very similar to the ia32 version.

56788625b6 Fix CPU profiling for Crankshaft. 
The main issue was due to multiple recompilations of functions.  Now
code objects are grouped by function using SFI object address.
JSFunction objects are no longer tracked, instead we track SFI object
moves. To pick a correct code version, we now sample return addresses
instead of JSFunction addresses.

tools/{linux|mac|windows}-tickprocessor scripts differentiate
between code optimization states for the same function
(using * and ~ prefixes introduced earlier).

DevTools CPU profiler treats all variants of function code as
a single function.

ll_prof treats each optimized variant as a separate entry, because
it can disassemble each one of them.

tickprocessor.py not updated -- it is deprecated and will be removed.

45c63ffa6a Add more generic version of reloc info padding to ensure enough space for reloc patching during deoptimization (fixes issue 1174). 
The old version only added extra space when we did indirect calls, but
the problem remains the same with normal calls that can be represented
as a single byte. When doing patching each call will always be at
least 2 bytes long because we use RUNTIME_ENTY as the reloc mode.

031062d246 Fix bug with input representation of HValueOf. 
The class did not correctly implement the RequiredInputRepresentation.
I changed this functions to be abstract so that all hydrogen classes
must implement it.

As a convention instructions with zero input operands return None as input
representation.

Instructions that can handle all input representations without converting before
also have None as required input representation (e.g. HTest)

All other instructions need a proper required input representation.

2ab5691ac1 ARM: Add support for just one string argument in the string add stub 
Having a string add stub which can handle a string in just one of the arguments is essencial for the type recording binary operation stub when expecting strings. Otherwise string added with e.g. smi will always call the runtime for a type transition which will be back to the same types as the transition code keeps it in string arguments when one argument is a string.

This fixes the regression (especially Delta Blue) caused by replacing the generic binary operation stub with the type recording binary operation stub in the ARM lithium code generator.

Before, the live ranges of the arguments extended to the call itself, and
they were pushed immediately before the call.  Now, they are spilled eagerly
as soon as their value is available and they are spilled to the right place.

The inlined runtime calls in the optimized backend are changed to work as in
all the other backends: they get their arguments untranslated and can choose
their own custom evaluation order.

963472c516 Change behavior of global declarations in the presence of setters. 
Call accessors in the global object prototype when initializing global
variables. Function declarations are special cased for compatibility
with Safari and setters are not called for them. If this special
casing was not done webkit layout tests would fail.

Make the declaration of global const variables in the presence of
callbacks a redeclaration error.

Handle const context slot declarations conflicting with a CALLBACK as
a redeclaration error. That is, unless it is on a context extension
object which is not a real object and therefore conceptually have no
accessors in prototype chains. Accessors in prototype chains of
context extension objects are explicitly ignored in SetProperty.

When deoptimizing to after an expression of the form (expr0 || expr1)

incorrectly see the value of the expression.

Handle the short-circuit binary operators specially in effect contexts.

6b4ff18b5b Properly process try/finally blocks. 
In some circumstances, try/finally block can actually catch the exception:

function f() {
  try {
    throw 42;
  } finally {
    return 0;
  }
}

Therefore when propagating exception to v8::TryCatch, we must be sure
there is no try/finally blocks as well.

When bulding the messages we should be more conservative and expect that
any v8::TryCatch with no JS try/catch in between can potentionally
be the right exception handler.

Plus various minor refactorings.

a8d4360d65 Make sure we always have room for patching the reloc info during lazy deoptimization (fixes issue 1156). 
Before we could have calls to builtins that would not be in the
relocation info since this used a register as target. Whenever we have
this case (from lithium codegen) we now emit a comment in the reloc
info.

4d07390196 Add access check when Object.keys is called on the global js proxy (fixes issue 1154) 
I will land access checks for a range of ES5 features in another patch (we added a bunch of cases like this in the past few weeks, i.e., cases where we simply use the global object instead of the js global proxy).

f2e38c6276 Refactor construction of polymorphic loads, stores, and calls. 
Rather than passing in a pair of unequal-length lists, pass the default
subgraph separately.  Construct the typecase from the top down rather than
the bottom up, so it doesn't need an intermediate zone list.

Also, change a basic block's 'last' instruction field to really be its last
instruction by correctly updating it when inserting and removing
instructions.
