      Description

        Calculated block's frequency could be NaN which can cause all kind of problems in Register_Allocate and PhaseBlockLayout phases.
        Specifically we hit SEGV with HS14 VM on Solaris 8 in qsort() because edge_order() method returns incorrect value
        for a block with NaN frequency.
