	cp/
	* cp-tree.h (TREE_INDIRECT_USING): Use TREE_LANG_FLAG_0 accessor.
	(ATTR_IS_DEPENDENT): Likewise.
	(ARGUMENT_PACK_INCOMPLETE_P): Use TREE_ADDRESSABLE instead of
	TREE_LANG_FLAG_0 on TREE_VECs.

	* tree.h (struct tree_base): Add union to make it possible to
	re-use the upper 4 bytes for tree codes that do not need as
	many flags as others.  Move visited and default_def_flag to
	common bits section in exchange for saturating_flag and
	unsigned_flag.  Add SSA name version and tree vec length
	fields here.
	(struct tree_vec): Remove length field here.
	(struct tree_ssa_name): Remove version field here.
