[X86] Add test coverage for #158649 (#159524)
Demonstrates the failure to keep avx512 mask predicate bit manipulation
patterns (based off the BMI1/BMI2/TBM style patterns) on the predicate
registers - unless the pattern is particularly complex the cost of
transferring to/from gpr outweighs any gains from better scalar
instructions

I've been rather random with the mask types for the tests, I can adjust
later on if there are particular cases of interest
