f6acb34d23 - Refactor the code that resolve basic block references to a TargetJITInfo 
method.
- Added synchronizeICache() to TargetJITInfo. It is called after each block
  of code is emitted to flush the icache. This ensures correct execution
  on targets that have separate dcache and icache.
- Added PPC / Mac OS X specific code to do icache flushing.

79cf9a5342 Fixed stack objects do not specify alignments, but their offsets are known. 
Use that information when doing the transformation to merge multiple loads
into a 128-bit load.

5987cfb7b1 X86 target specific DAG combine: turn build_vector (load x), (load x+4), 
(load x+8), (load x+12), <0, 1, 2, 3> to a single 128-bit load (aligned and
unaligned).

e.g.

__m128 test(float a, float b, float c, float d) {
  return _mm_set_ps(d, c, b, a);
}

_test:
        movups 4(%esp), %xmm0
