https://gcc.gnu.org/ml/gcc-patches/2017-10/msg00899.html
	PR middle-end/82546
	gcc/
	* tree.c (tree_code_size): Reformat.  Punt to lang hook for unknown
	TYPE nodes.
	gcc/cp/
	* cp-objcp-common.c (cp_tree_size): Reformat.  Adjust returns size
	of TYPE nodes.
	gcc/objc/
	* objc-act.c (objc_common_tree_size): Return size of TYPE nodes.
