This still lower to the same intrinsics as before.
This is preparation for bounds checking the immediate on the avx version of the builtin so we don't pass illegal immediates into the backend. Since SSE uses a smaller size immediate its not possible to bounds check when using a shared builtin. Rather than creating a clang specific builtin for the different immediate, I decided (after consulting with Chandler) that it was better to match gcc.

Instructions from __nodebug__ functions don't have file:line
information even when inlined into no-nodebug functions. As a result,
intrinsics (SSE and other) from <*intrin.h> clang headers _never_
have file:line information.
With this change, an instruction without !dbg metadata gets one from
the call instruction when inlined.
Fixes PR19001.

Summary:
Most of the clang header patch by Simon Pilgrim @ SCEE.
Also fixed (or added) clang tests for these intrinsics.
LLVM tests to make sure we get the blend instruction out of these
shufflevectors are at http://reviews.llvm.org/D3600

Now, all extract & insert intrinsics should have the correct and operation
to ignore higher bits.

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

Without -ffreestanding, clang tries to seek /usr/include/stdlib.h in host filesystem, even on Windows hosts.
