5a9b2b3c5f 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.

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.

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.

c10267f1fa Refactor HCheckInstanceType to allow mask/tag tests. 
This allows us to get rid of totally fake LAST_STRING_TYPE and makes
it possible to test for symbols.

I considered splitting HCheckInstanceType into two instructions, but
it seems nice to be able to hide the instance type implementation
details from the hydrogen level.

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.

The only difference to revision 7763 is the implementation in the
builtins file for arm and x64, plus a move of Array.prototype.toString
and Array.prototype.toLocaleString from should throw on null or
undefined to the non generic test cases in the function-call test (due
to us not currently supporting generic cases with these to functions)

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).

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.)

1f96aa3772 ARM: Enhance the hardfloat support 
The "simple" function with inline assembly for detecting hardfloat have been changed to handle compiling without VFP and with thumb.

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

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.

2d8556827e Fix x64 typefeedback for property assignments. 
There was not ast-id recorded. I removed the default arguments
for the helper functions that emit IC calls to make sure
we are not missing other places.

0f6f6a0e93 Initialize ThreadLocalTop. 
ThreadLocalTop used to be static and was zero initialized by the
linker. With isolates we have to give it a constructor.

3b445f14f8 X64 tweaks. 
Use movapd instead of movsd to move between xmm registers. Avoids partial
register writes and potential stalls.

Use xorps instead of xorpd to zero a register. Same effect and latency, but
one byte smaller.

dab8f48ebc ARM: Implement correct rounding in the lithium codegenerator. 
This patch provides testing for values that have a fraction part of 0.5 and uses a different rounding method for them. The original method of VFPTruncating the value with round-to-nearest is not correct because it does not round to the larger number in case of a tie.
