8118 (push_parm_decl): Don't update parm_order.
8119 (clear_parm_order): Rename mark_forward_parm_decls. Issue the

8123 (get_parm_info): Don't use gettags or getdecls. No need to
8124 extract non-parms from the parms list, or reorganize the parms

8127 appearing more than once in said parameter list. Collapse

8136 from the parms chain, nor to store them back afterward. Move
