While we don't have to flush icache on Intel CPUs when we patch code we still have to call CPU::FlushICache() to notify Valgrind otherwise Valgrind will run incorrect translations which will lead to strange crashes.

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
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.

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.

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).

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.

When processing register contraints we used to add writable input operands
also as temp operands to the same instruction.

This does not seem necessary since we create a fresh virtual register
for writable inputs and insert a definition in the gap before the instruction.
