simd/archsimd: use V(P)MOVMSK for mask ToBits if possible
VPMOVMSKB, VMOVMSKPS, and VMOVMSKPD moves AVX1/2-style masks to
integer registers, similar to VPMOV[BWDQ]2M (which moves to mask
registers). The former is available on AVX1/2, the latter requires
AVX512. So use the former if it is supported, i.e. for 128- and
256-bit vectors with 8-, 32-, and 64-bit elements (16-bit elements
always require AVX512).
