27f0ae7aad 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.

11a4cb5718 Introduce extra IC state to record additional feedback from IC-s. 
Extra IC state is only two bits and only supported for call IC-s for
now. To change its extra state an IC stub jumps to a new miss stub
that goes to runtime as usual but then instead of going megamorphic
generates a monomorphic stub with the updated state.

is that the mozilla ones were caused by the safe-point table problem
and the deoptimization ones are fixed by adding support for mod and
div.

3d245133a3 Enable compilation of very simple functions in x64 crankshaft. 
This change includes support for safepointtables and adding deoptimization info (but not for deoptimizing).

Implemented crankshaft functions:
CallCode
GenerateSafepointTable
RegisterEnvironmentForDeoptimization
EmitGoto


This change allows us to compile very simple functions with crankshaft:
An empty function
A function returning a constant.
A function returning a parameter.

There is 6 disabled tests that require us to be able to deoptimize
which is currently not supported.

87e82b0452 Remove the remaining LOperand-members from concrete LIR instructions. 
This change introduces the third template parameters for LIR instructions
to specify the number of temp-operands. This is one step towards
removing the instruction-summaries.

I also added hydrogen-accessors in more places and refactored
the LIR-branch instructions to have common super-classes to 
avoid code duplication.

Added MUST_USE_RESULT to the functions that record uses
and definitions so that all LOperands are stored in the
LIR instructions (and not only in the summaries).

437914da90 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.
