    tree-optimization/113373 - add missing LC PHIs for live operations

    The following makes reduction epilogue code generation happy by properly
    adding LC PHIs to the exit blocks for multiple exit vectorized loops.

    Some refactoring might make the flow easier to follow but I've refrained
    from doing that with this patch.

    I've kept some fixes in reduction epilogue generation from the earlier
    attempt fixing this PR.

            PR tree-optimization/113373
            * tree-vect-loop-manip.cc (slpeel_tree_duplicate_loop_to_edge_c=
fg):
            Create LC PHIs in the exit blocks where necessary.
            * tree-vect-loop.cc (vectorizable_live_operation): Do not try
            to handle missing LC PHIs.
            (find_connected_edge): Remove.
            (vect_create_epilog_for_reduction): Cleanup use of auto_vec.
