Get rid of storelv4si builtin as it can be expressed directly. This is general
...
goodness because it provides opportunites to cleanup things. For example,
uint64_t t1(__m128i vA)
{
uint64_t Alo;
_mm_storel_epi64((__m128i*)&Alo, vA);
return Alo;
}
was generating
movq %xmm0, -8(%rbp)
movq -8(%rbp), %rax
and now generates
movd %xmm0, %rax

Tweak *mmintrin.h so that they don't make any bad assumptions about alignment (which probably has little effect in practice, but better to get it right). Make the load in _mm_loadh_pi and _mm_loadl_pi a single LLVM IR instruction to make optimizing easier for CodeGen.
