    vect: Treat VMAT_ELEMENTWISE as scalar load in costing [PR110776]

    PR110776 exposes one issue that we could query unaligned
    load for vector type but actually no unaligned vector load
    is supported there.  The reason is that the costed load is
    with single-lane vector type and its memory access type is
    VMAT_ELEMENTWISE, we actually take it as scalar load and
    set its alignment_support_scheme as dr_unaligned_supported.

    To avoid the ICE as exposed, following Rich's suggestion,
    this patch is to make VMAT_ELEMENTWISE be costed as scalar
    load.
