tree-optimization/112450 - avoid AVX512 style masking for BImode masks
The following avoids running into the AVX512 style masking code for
RVV which would theoretically be able to handle it if I were not
relying on integer mode maskness in vect_get_loop_mask. While that's
easy to fix (patch in PR), the preference is to not have AVX512 style
masking for RVV, thus the following.
* tree-vect-loop.cc (vect_verify_full_masking_avx512):
Check we have integer mode masks as required by
vect_get_loop_mask.
