compiler generates code with using avx512 zmm operations 4
times (16x4=64) and remaining 8 iterations are handled by
routine mov operations with EAX register. wouldn't it be
better if it uses ymm for remaining 8 iterations as it does
when iteration count is between 8 and 15. same for xmm and so
on.</div>
