Chad Rosier 87622b8b84 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

NAKAMURA Takumi 3f62af76b9 test/CodeGen/sse-builtins.c: Make this host-independent to unbreak posix-unlike hosts. 
Without -ffreestanding, clang tries to seek /usr/include/stdlib.h in host filesystem, even on Windows hosts.

Eli Friedman 9bb51adcce 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.
