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.
