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

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.

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.
