Hans Wennborg 2ed8880346 Intrin.h: fix definitions of _Interlocked{In,De}crement16 
The declarations seem correct, but the definitions were using
chars instead of shorts.

Hans Wennborg 854f7d34ec Add implementations of _cpuid and _xgetbv to Intrin.h 
The _cpuid() implementation is the same as in lib/Headers/cpuid.h
with the parameter names adjusted to match the interface.

_xgetbv just does what the Intel manual says.

Reid Kleckner 00d33a5cb1 Add implementations of the MSVC barrier intrinsics 
Summary:
These are deprecated in VS 2012 according to MSDN.  They don't actually
compile down to any code.  They prevent the compiler from reordering
memory accesses across the barrier, which is what a memory-clobbering
volatile asm does.

Eric Christopher d1428bf635 Add initial clang targeted compatible decls for Intrin.h. Step towards 
a windows compatible builtin header.

Currently uses x86intrin.h for implementing intel intrinsics in a clang
specific manner.
