Craig Topper 8c8e83a15f [X86] Add support for 'amdfam17h' to __builtin_cpu_is to match gcc.
The compiler-rt implementation already supported it, it just wasn't exposed.

Craig Topper 699ae0c173 [X86] Implement __builtin_cpu_is
This patch adds support for __builtin_cpu_is. I've tried to match the strings supported to the latest version of gcc.

Craig Topper 41a550ccfa [X86] Support 'avx5124vnniw' and 'avx5124fmaps' for __builtin_cpu_supports.
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.

Benjamin Kramer f4c520d5d2 Add all the avx512 flavors to __builtin_cpu_supports's list.
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?

Eric Christopher 99af5b2ea7 Handle target builtin options that are all required rather than
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.

Eric Christopher c276e80022 Mark this test as requiring and x86 registered target.

Eric Christopher 15709991d0 Add an error when calling a builtin that requires features that don't
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.
