    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
        =3D 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_alignmen=
t.

            dr_unaligned_supported for gather-scatter accesses.
