    tree-optimization/95717 - fix SSA update for vectorizer epilogue

    This fixes yet another issue with the custom SSA updating in the
    vectorizer when we copy from the non-if-converted loop.  We must
    not mess with current defs before we updated the BB copies.

            Move BB SSA updating before exit/latch PHI current def copying.
