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.

Reviewer: Craig Topper.
Differential Revision: https://reviews.llvm.org/D23108

Craig Topper 6bcbf5338c [AVX512] Cleanup FMA operand order in patterns to match the VEX versions and to really be 213, 231, and 132.

Craig Topper 5c913e84df [AVX512] Use VMOVAPSZ128rr/VMOVAPS256rr for VR128X/VR256X physreg moves when VLX is supported. 
Ideally we would use VEX encoded moves instead of EVEX if the high 16 registers aren't referenced, but this a good first step.

Elena Demikhovsky 86528270b9 AVX-512: Fixed a bug in FMA instruction selection on KNL 
The FMA instruction was selected from AVX2 set instead of AVX-512

Igor Breger 756c289dd8 AVX512: Change VPMOVB2M DAG lowering , use CVT2MASK node instead TRUNCATE. 
Fix TRUNCATE lowering vector to vector i1, use LSB and not MSB.
Implement VPMOVB/W/D/Q2M intrinsic.

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.
