Truncate rather than round to nearest when performing float-to-integer
...
conversions for external array types, which implement the Typed Array
spec. The new code paths are for SSE3 and SSE2 capable processors.
The code for non-SSE2 processors is unchanged for now. The ARM port
appears to already be correct.
Moved the generation of the external array load and store intrinsics
to the stub cache (on all platforms) so that they are generated at run
time and can take advantage of CPU features.
This functionality is covered by the array-unit-tests.html test in the
WebGL conformance test suite:
http://khronos.org/webgl/wiki/Testing/Conformance
https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/conformance/array-unit-tests.html
Manually verified all of the SSE3/SSE2/non-SSE2 code paths by enabling
each in turn. Tested in Chromium on 32-bit Mac OS X and 64-bit Linux.

Extra IC state is only two bits and only supported for call IC-s for

that goes to runtime as usual but then instead of going megamorphic

Change the algorithm and generated code for parallel moves on IA32.
...
Instead of spilling and then immediately restoring eax to resolve
memory to memory moves, the gap move resolver now tracks registers
that are known to be free and uses one if available. If not it spills
but restores lazily when the spilled value is needed or at the end of
the algorithm.
Instead of using esi for resolving cycles and assuming it is free to
overwrite because it can be rematerialized, the gap move resolver now
resolves cycles using swaps, possibly using a free register as above.
The algorithm is also changed to be simpler: a recursive depth-first
traversal of the move dependence graph. It uses a list of moves to be
performed (because it mutates the moves themselves), but does not use
any auxiliary structure other than the control stack. It does not
build up a separate list of scheduled moves to be interpreted by the
code generate, but emits code on the fly.

Fix GC issue in instanceof stub
...
The the call of the builtin in InstanceofStub was not correctly protected with an internal frame leading to the return address being handled as a pointer during GC.
Marked the Instanceof stub as allowing stub calls (the RecordWriteStub was removed some days ago).
This issue was not caught by the assertion designed for this when debug mode is run with --debug-code (which out tests always does) as generating code for Abort set the allow stub calls flag to true. This has been fixed by restoring the allow stub calls flag correctly.

Use a separate marker value to allocate the arguments object on deoptimzation.
...
Before we used the hole value for this purpose, but this does not work once we
start using the hole value for other purposes in the optimizing compiler.
