Manman Ren 5750c1c07e X86 SSE Intrinsics: update header for sqrt_ss, rsqrt_ss and rcp_ss. 
There intrinsics pass through the upper FP values from the input.

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

Craig Topper 74c17c65e4 Correctly check argument types for some vector macros in smmintrin.h. Put parentheses around uses of vector macro arguments.

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.
