5848 (push_parm_decl): Don't update parm_order.
5849 (clear_parm_order): Rename mark_forward_parm_decls. Issue the

5853 (get_parm_info): Don't use gettags or getdecls. No need to
5854 extract non-parms from the parms list, or reorganize the parms

5857 appearing more than once in said parameter list. Collapse

5866 from the parms chain, nor to store them back afterward. Move
