[X86] Cleanup fma tests a little bit. NFC. Reformat, isolate 213->231 xform, actually --check-prefix CHECK, and deduplicate the FMA intrinsic tests (FMA3 in AMD-land). llvm-svn: 240615

[X86] Accept hasAVX512() as well as hasFMA() when generating FMA. We don't always have FMA, for example when using 'clang -mavx512f' without an explicit CPU. Also check for an explicit +avx512f instead of CPUs in a couple related tests. llvm-svn: 240616
