        CastPP, CheckCastPP and Proj nodes are not "dead" loop safe after
        the putback 20061023120554.jrose.dolphin-cleanups which added
        new mmethods Ideal_allocation(), Ideal_klass(), Ideal_length().
        These methods could bypass the nodes chain to get a klass or
        an array's length from inputs of Allocation node:
        Allocate <- Proj <- CheckCastPP.

        As result dead data loop could be created.
