    Mark rtl_avoid_store_forwarding functions final override
    
    It is customary to mark the gate and execute functions of the classes
    representing passes as final override but this is missing in
    pass_rtl_avoid_store_forwarding.  This patch adds it which also
    silences a clang warning about it.

            pass_rtl_avoid_store_forwarding): Mark member function gate as
            final override.
