Summary:
We should always be able to accept AVX512 registers and instructions in llvm-mc. The only subtarget mode that should be checked is 16-bit vs 32-bit vs 64-bit mode.
I've also removed all the mattr/mcpu lines from test RUN lines to be consistent with this. Most were due to AVX512, but a few were for other features.

Committing on behalf of Coby Tayree: After check-all and LGTM
Desc:
AVX512 allows dest operand to be followed by an op-mask register specifier ('{k<num>}', which in turn may be followed by a merging/zeroing specifier ('{z}')
Currently, the following forms are allowed:
{k<num>}
{k<num>}{z}
This patch allows the following forms:
{z}{k<num>}
and ignores the next form:
{z}
Justification would be quite simple - GCC
