	(pending_inline): Call expand_body.
	(handler): Adjust calls to finish_handler_parms and
	finish_handler.
	(handler_args): Don't call expand_start_catch_block.  Return the
	catch parameter.  * pt.c (tsubst_expr): Adjust HANDLER handling.
	* parse.c: Regenerated.
	* rtti.c (synthesize_tinfo_fn): Call finish_function.
	* semantics.c (do_pushlevel): Give it external linkage.  Build
	SCOPE_STMTs.
