Evan Cheng 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.

Evan Cheng 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
        ret

Chris Lattner f3b5b92e58 Don't pass target name into TargetData anymore, it is never used or needed.
