Why would this be? The element mode doesn't matter at all for bitwise
operations. Just like there's no VPANDB / VPANDW, but VPANDD/VPANDQ are quite
fine to use on vectors of QI or HI. Afaict the existence of VPAND{D,Q} in
AVX512 (as opposed to {,V}PAND in MMX/SSE2/AVX) is merely an oddity resulting
from EVEX.W handling (besides of course the element width's effect on embedded
broadcasting).
