        nested_in_vect_loop_p (don't allow changing the order in this case).
        (vect_is_simple_reduction): Takes a loop_vec_info as argument instead

        update their loop_vinfo.  Order of BB traversal now matters - call
        dfs_enumerate_from with bb_in_loop_p.
        (destroy_loop_vec_info): Takes additional argument to control whether
        stmt_vinfo of the loop stmts should be destroyed as well.

        this is an inner-loop reduction in outer-loop vectorization.

        Same code as what used to be vect_analyze_scalar_cycles, only with
        additional argument loop, and loop_info passed to
        vect_is_simple_reduction instead of loop.
        (vect_analyze_scalar_cycles): Code factored out into
        vect_analyze_scalar_cycles_1. Call it for each relevant loop-nest.
        Updated documentation.
        (analyze_operations): Check for inner-loop loop-closed exit-phis during
        outer-loop vectorization that are live or not used in the outerloop,
        cause this requires special handling.
        (vect_enhance_data_refs_alignment): Don't consider versioning for
        nested-loops.
        (vect_analyze_data_refs): Check that there are no datarefs in the
        inner-loop.
        (vect_mark_stmts_to_be_vectorized): Also consider vect_used_in_outer

        in the inner-loop when doing outer-loop vectorization. Add
        documentation and printout.
        (vect_recog_dot_prod_pattern): Likewise. Also add check for
        GIMPLE_MODIFY_STMT (in case we encounter a phi in the loop).
