[PATCH] Small pre-AVX512F optimization

Hi! I've noticed that expand_vec_perm_1 completely uselessly builds GC garbage (CONST_VECTOR at least) when AVX512F isn't enabled at all. Ok to just call it for AVX512F? Even better would be to check the modes first too depending on target (AVX512F will only handle V{8D,16S}{I,F}mode, AVX512BW w
