    tree-optimization/109573 - avoid ICEing on unexpected live def

    The following relaxes the assert in vectorizable_live_operation
    where we catch currently unhandled cases to also allow an
    intermediate copy as it happens here but also relax the assert
    to checking only.

            PR tree-optimization/109573
            * tree-vect-loop.c (vectorizable_live_operation): Allow
            unhandled SSA copy as well.  Demote assert to checking only.

            * g++.dg/vect/pr109573.cc: New testcase.
