This patch is a part two of two reviews, one for the clang and the other for LLVM.
In this patch, I covered the clang side, by introducing the intrinsic to the front end.
This is done by creating a generic replacement.

x86 has undef SSE/AVX intrinsics that should represent a bogus register operand.
This is not the same as LLVM's undef value which can take on multiple bit patterns.
There are better solutions / follow-ups to this discussed here:

...but this should prevent miscompiles with a one-line code change.

Unfortunately, the backend currently doesn't fold masks into the instructions correctly when they come from these shufflevectors. I'll work on that in a future commit.

The X86 clang/test/CodeGen/*builtins.c tests define the mm_malloc.h include
guard as a hack for avoiding its inclusion (mm_malloc.h requires a hosted
environment since it expects stdlib.h to be available - which is not the case
in these internal clang codegen tests).
This patch removes this hack and instead passes -ffreestanding to clang cc1.
