The compiler-rt implementation already supported it, it just wasn't exposed.

This patch adds support for __builtin_cpu_is. I've tried to match the strings supported to the latest version of gcc.

They still need to be implemented in the intrinsics, the command line, and the backend. But this change isn't dependent on any of that and resolves a TODO.

This is matching what trunk gcc is accepting. Also adds a missing ssse3
case. PR27779. The amount of duplication here is annoying, maybe it
should be factored into a separate .def file?

only one of a group of possibilities.
This changes the syntax in the builtin files to represent:
, as the and operator
| as the or operator
The former syntax matches how the backend tablegen files represent
multiple subtarget features being required.
Updated the builtin and intrinsic headers accordingly for the new
syntax.

match the feature set of the function that they're being called from.
This ensures that we can effectively diagnose some[1] code that would
instead ICE in the backend with a failure to select message.
Example:
__m128d foo(__m128d a, __m128d b) {
return __builtin_ia32_addsubps(b, a);
}
compiled for normal x86_64 via:
clang -target x86_64-linux-gnu -c
would fail to compile in the back end because the normal subtarget
features for x86_64 only include sse2 and the builtin requires sse3.
[1] We're still not erroring on:
__m128i bar(__m128i const *p) { return _mm_lddqu_si128(p); }
where we should fail and error on an always_inline function being
inlined into a function that doesn't support the subtarget features
required.
