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.

[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.
