gcc/cp/
	* class.c (cp_fold_obj_type_ref): Call cgraph_get_node instead of
	cgraph_get_create_node.
	* decl2.c (cp_write_global_declarations): Call cgraph_get_node
	instead of cgraph_get_create_node.
	* method.c (make_alias_for_thunk): Call cgraph_get_node
	instead of cgraph_get_create_node, assert it returns non-NULL.
	(use_thunk): Likewise.
	* optimize.c (maybe_clone_body): Call cgraph_same_body_alias only
	when flag_syntax_only is not set.  Call cgraph_get_node instead of
	cgraph_get_create_node.
	(maybe_clone_body): Call cgraph_get_node instead of
	cgraph_get_create_node.
