--- Comment #3 from Alexander Fomin <afomin.mailbox at gmail dot com> ---
There is another problem with the same pattern.
Suppose an V16SF insn mode and AVX512F target (e.g. KNL).
We'll emit something like vandps %zmm1, %zmm2, %zmm3; however, v<logic>ps
family requires AVX512VL and/or AVX512DQ CPUID.
