This patch enables insertion of To{Slow,Fast}Properties around a group

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.

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.

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.

Fixes the build for the shell on illumos and Solaris. -D__C99FEATURES__ was added to mirror how the build is done on the normal platform. The changes in the platform code are a follow up to a prior review and has the Solaris implementation be more similar to the Linux version as opposed to the FreeBSD.

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.

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.

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.

Better placement of argument pushing for a few hydrogen call instructions.

Where it's simple to do so (keyed calls, calls to unknown global variables,
calls to local variables and non-property/non-variable expressions), end the

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.

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.

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).

Before, they had no extra slots and an extension object with one named

an extra slot for the thrown object. This increases the size of the context

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...

"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!

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.

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.

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.

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.

* 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.

Simple support for const variables in Crankshaft.
...
The approach is to handle the common case in the optimizing
compiler and to bailout for the rare corner cases.
This is done by initializing all local const-variables with
the hole value and disallowing any use of the hole value statically.

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.

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.

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.

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.

Remove wrong assert to fix a debug crash with arguments object.
...
We don't need to assert the existence of a length-property of the
arguments object because it is not a JSArray, but just a normal JSObject.

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.

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.

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... ;-)

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. Currently, the only array types supported by the MEGAMORPHIC stub are fast elements for objects and JSArrays.

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?

"Foreign", to avoid confusion.

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.

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.

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.

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.

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).

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.)

The SCons setting for the float abi now follows then naming used by the GCC -mfloat-abi and soft has been added.

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.

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.
