    A few missing SLP node passings to vector costing
    
    The following fixes another few missed cases to pass a SLP node
    instead of a stmt_info.
    
            * tree-vect-loop.cc (vectorizable_reduction): Pass the
            appropriate SLP node for costing of single-def-use-cycle
            operations.
            (vectorizable_live_operation): Pass the SLP node to the
            costing hook.
            * tree-vect-stmts.cc (vectorizable_bswap): Likewise.
            (vectorizable_store): Likewise.
