	* tree.c (build_common_tree_nodes): Also initialize size_type_node.
	Call set_sizetype from here.

	c-family/
	* c-common.c (c_common_nodes_and_builtins): Do not set
	size_type_node or call set_sizetype.

	go/
	* go-lang.c (go_langhook_init): Do not set
	size_type_node or call set_sizetype.

	fortran/
	* f95-lang.c (gfc_init_decl_processing): Do not set
	size_type_node or call set_sizetype.

	java/
	* decl.c (java_init_decl_processing): Properly initialize
	size_type_node.

	lto/
	* lto-lang.c (lto_init): Do not set
	size_type_node or call set_sizetype.

	ada/
	* gcc-interface/misc.c (gnat_init): Do not set
	size_type_node or call set_sizetype.
