[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.

AVX-512: Added FMA intrinsics with rounding mode
...
By Asaf Badouh and Elena Demikhovsky
Added special nodes for rounding: FMADD_RND, FMSUB_RND..
It will prevent merge between nodes with rounding and other standard nodes.
