    tree-optimization/116575 - avoid ICE with SLP mask_load_lane

    The following avoids performing re-discovery with single lanes in
    the attempt to for the use of mask_load_lane as rediscovery will
    fail since a single lane of a mask load will appear permuted which
    isn't supported.

            PR tree-optimization/116575
            * tree-vect-slp.cc (vect_analyze_slp): Properly compute
            the mask argument for vect_load/store_lanes_supported.
            When the load is masked for now avoid rediscovery.

            * gcc.dg/vect/pr116575.c: New testcase.=
