Vyacheslav Klochkov 6daefcf626 X86-FMA3: Implemented commute transformation for EVEX/AVX512 FMA3 opcodes.
This helped to improved memory-folding and register coalescing optimizations.

Also, this patch fixed the tracker #17229.

Ahmed Bougacha f1eccbecf8 [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.

Elena Demikhovsky 7b0dd39db6 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.
