Move sha intrinsics to immintrin.h
...
This is consistent with ICC and Intel's SHA-enabled GCC version.

Add C intrinsics for Intel SHA Extensions
...
Intrinsics added shaintrin.h, which is included from x86intrin.h if __SHA__ is
enabled. SHA implies SSE2, which is needed for the __m128i type.
Also add the -msha/-mno-sha option.

Add PRFCHW intrinsic support
...
- Add head 'prfchwintrin.h' to define '_m_prefetchw' which is mapped to
LLVM/clang prefetch builtin
- Add option '-mprfchw' to enable PRFCHW feature and pre-define '__PRFCHW__'

Add an ammintrin.h header for SSE4a intrinsics.
...
This is a clean-room implementation based on public documentation and
I tried to validate it as much as possible against gcc.

Add 3dNOW intrinsic header to x86intrin.h, conditioned on __3dNOW__ to
...
match the behavior of GCC. Also add a test for these intrinsics, which
apparently have *zero* tests. =[ Not surprisingly, Clang crashed when
compiling these.
Fix the bug in CodeGen where we failed to bitcast the argument type to
x86mmx prior to calling the LLVM intrinsic. This fixes an assert on the
new 3dnow-builtins.c test.
This is one issue impacting the efforts to get Clang to emulate the
Microsoft intrinsics headers -- 3dnow intrinsics are implictitly made
available there.

Add x86intrin.h which is generic x86 intrinsics for more than just Intel. Thus
...
far, this just #include's immintrin.h for compatibility.
