fb2317b63b New snapshot framework. Doesn't work on ARM yet (code targets
are different).  Is able to deserialize the whole heap and run
some stuff.  Not available as the primary snapshot system yet.

dcee14979f Generate more compact XOR on 64-bit architecture when using xor to zero out registers.
When using xor to zero a 64-bit register, generate 32-bit instruction instead.
(according to Intel 64-bit mode coding guidelines) 

previous code for zeroing RAX:
  xor rax, rax  

==>

new code for zeroing RAX: 
  xor eax, eax

The 32-bit operand form has the same semantics: It also zeroes the upper 
32-bit of rax and its encoding uses 1 byte less.

d5f00cf6cc Add optimized ICs for new CanvasArray types introduced in WebGL
specification under development. This is a follow-on CL to
http://codereview.chromium.org/293023 .

Based on review feedback, defined the behavior of storing NaN and
+/-Infinity into external arrays of integer types as storing 0. Added
test cases. Added fucomi instruction to assembler. Fixed bug in
KeyedLoadIC::GenerateExternalArray when allocation of HeapNumber
failed. Fixed bug in encoding of 16-bit immediate arithmetic
instructions in 64-bit port.

Removed raising of exceptions for negative array indices passed to
external arrays and associated tests. Based on current discussion in
WebGL working group, will probably end up removing the exception
throwing altogether.

46e6297e3e Added infrastructure for optimizing new CanvasArray types in WebGL
specification under development. The optimizations are patterned after
those previously done for CanvasPixelArray. This CL adds all of the
necessary framework but continues to use the generic KeyedLoadIC and
KeyedStoreIC code, to create a baseline for benchmarking purposes. The
next CL will add the optimized ICs to ic-ia32.cc and ic-x64.cc.

These new CanvasArray types have different semantics than
CanvasPixelArray; out-of-range values are clamped via C cast
semantics, which is cheaper than the clamping behavior specified by
CanvasPixelArray. Out-of-range indices raise exceptions instead of
being silently ignored.

As part of this work, pulled FloatingPointHelper::AllocateHeapNumber
up to MacroAssembler on ia32 and x64 platforms. Slightly refactored
KeyedLoadIC and KeyedStoreIC. Fixed encoding for fistp_d on x64 and
added a few more instructions that are needed for the new ICs. The
test cases in test-api.cc have been verified by hand to exercise all
of the generated code paths in the forthcoming specialized ICs.

8105ae3106 Optimize calls to GenericBinaryStub.
The calls to GenericBinaryStub can now pass the arguments in registers instead of on the stack. It is supported for ADD, SUB, MUL and DIV. The convention in GenericBinaryStub is not changed so the left operand is passed in edx and the right one in eax. When the stub contains smi code arguments are always passed on the stack as the smi code has to have left and right operands on eax and ebx, so moving from edx,eax to eax,ebx is not worth it and the smi code also trashes the registers so if arguments where passed in registers they would have to be saved on the stack anyway.

Added flags to disable the use of certain Intel CPU features to make it easier to test different code paths.

We could not handle functions with no explicit return statement.  I
added support for that as well.  The place was hard to find because
code was left out from the codegenerator with no TODO comment.  We
need to make sure to comment if we leave out code when porting
something. :-)
