// AVX 512 cmpeq returns a bit mask instead of a vector mask.
// This should simplify things but the logic doesn't seem to be working.
// The problem appears to be related to the test to skip a hash if it isn't
// to be used. Skipping the test for all 8 way hashes seems to have
// fixed it. The hash selection blending works if the hash is produced
// but the hash wasn't being produced when it should.
// Both decisions are based on the same data, the __mmask8. It works
// as a blend mask but not in a logical comparison, maybe the type is the
// problem. Maybe a cast to int or movm is needed to make it work.
// It's now moot because the hash can only be skipped 1 in 256 iterations
// when hashing parallel 8 ways.
// The performance impact of the workaround should be negligible.
// It's a problem for another day.
