Ben Langmuir 6efe3a886e Move sha intrinsics to immintrin.h
This is consistent with ICC and Intel's SHA-enabled GCC version.

Ben Langmuir 58078d0103 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.

Michael Liao 74f4eaf4dc 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__'

Craig Topper 9fd12db1c0 Update FIXME. ABM is already covered by LZCNT and POPCNT.

Benjamin Kramer ba6e2528fa 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.

Chandler Carruth a2a5410e6d 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.

Craig Topper ba418d8e91 Remove an accidental change from r147370. Would only break if the new fma4 flag was used.

Craig Topper ffdb46ceef Add FMA4 feature flag. Intrinsics coming soon. Also make sse4a feature flag imply sse3. Matches gcc behavior.

Craig Topper 1de8348db7 Add popcnt feature flag to match gcc. This flag is implied when sse42 is enabled, but can be disabled separately. Move popcnt intrinsics to popcntintrin.h to match gcc.

Nick Lewycky 0b84914da0 Add x86intrin.h which is generic x86 intrinsics for more than just Intel. Thus
far, this just #include's immintrin.h for compatibility.
