    rtl-optimization/105559 - avoid quadratic behavior in delete_insn_and_e=
dges

    When the insn to delete is a debug insn there's no point in figuring
    out whether it might be the last real insn and thus we have to purge
    dead edges.

            * cfgrtl.c (delete_insn_and_edges): Only perform search to BB_E=
ND
            for non-debug insns.
