[PATCH] x86/AVX512: improve generated code for mask-to-vector-register conversions

Conversion of comparison results to full vectors does, when VPMOVM2* are unavailable, not require any intermediate VMOVDQ{A,U}*: Simply use embedded masking on VPTERNLOG* right away, which is available with AVX512F (while VPMOVM2{D,Q} are available only with AVX512DQ). Note that the chosen immedia
