Looks like we're trying to compute:
alignment_support_scheme
= vect_supportable_dr_alignment (first_dr_info, false);
gcc_assert (alignment_support_scheme);
even for VMAT_GATHER_SCATTER, which always accesses individual
elements. Guess we should set alignment_support_scheme to
dr_unaligned_supported instead of calling
vect_supportable_dr_alignment.
The target hook is probably incorrect for SVE + -mstrict-align.
