vect: ICE: in vectorizable_load, at tree-vect-stmts.c:9173 [PR94398]
In the testcase for PR94398, 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.
Here we should set alignment_support_scheme to dr_unaligned_supported
the gather/scatter case instead of calling vect_supportable_dr_alignment.

* tree-vect-stmts.c (vectorizable_store): Instead of calling
vect_supportable_dr_alignment, set alignment_support_scheme to
dr_unaligned_supported for gather-scatter accesses.
(vectorizable_load): Likewise.
