    tree-optimization/117767 - VMAT_STRIDED_SLP and alignment

    This plugs another hole in alignment checking with VMAT_STRIDED_SLP.
    When using an alternate load or store type we have to check whether
    that's supported with respect to required vector alignment.

            PR tree-optimization/117767
            * tree-vect-stmts.cc (vectorizable_store): Check for supported
            alignment before using a an alternate store vector type.
            (vectorizable_load): Likewise for loads.

            * gcc.dg/vect/pr117767.c: New testcase.
