    tree-optimization/111950 - vectorizer loop copying

    The following simplifies LC-PHI arg population during epilog peeling,
    thereby fixing the testcase in this PR.

(slpeel_duplicate_current_defs_from_edges):
            Remove.

            LC-PHIs for invariant values.
            (vect_do_peeling): Materialize PHI arguments for the edge
            around the epilog from the PHI defs of the main loop exit.
