    Fix missed peeling for gaps with SLP load-lanes
    
    The following disables peeling for gap avoidance with using smaller
    vector accesses when using load-lanes.
    
            * tree-vect-stmts.cc (get_group_load_store_type): Only disable
            peeling for gaps by using smaller vectors when not using
            load-lanes.
