        * combine.c (struct rtx_subst_pair): Define unconditionally.
        (propagate_for_debug_subst): Likewise.  If not AUTO_INC_DEC,
        copy_rtx pair->to instead of cleanup_auto_inc_dec it.
        Call make_compound_operation on pair->to.
        (propagate_for_debug): Don't call make_compound_operation here.
        Always use simplify_replace_fn_rtx.
