	* tree.c (WALK_SUBTREE): Call walk_tree_1.
	(walk_type_fields): Take lh parameter.
	(walk_tree): Rename to ...
	(walk_tree_1): ... this.  Do not call the walk_subtrees
	langhook but the now passed callback.  Pass lh on recursion.
	(walk_tree_without_duplicates): Rename to ...
	(walk_tree_without_duplicates_1): ... this.  Take lh parameter
	and call walk_tree_1.
	* tree.h (walk_tree_lh): New typedef.
	(walk_tree_1): Declare.
	(walk_tree_without_duplicates_1): Likewise.
	(walk_tree): New define to walk_tree_1 with NULL lh parameter.
	(walk_tree_without_duplicates): New define to
	walk_tree_without_duplicates_1 with NULL lh parameter.
	* langhooks.c (lhd_tree_inlining_walk_subtrees): Remove.
	* langhooks.h (lang_hooks_for_tree_inlining): Remove walk_subtrees
	langhook.
	* langhooks-def.h (lhd_tree_inlining_walk_subtrees): Remove.
	(LANG_HOOKS_TREE_INLINING_WALK_SUBTREES): Likewise.
	(LANG_HOOKS_TREE_INLINING_INITIALIZER): Remove walk_subtrees
	initializer.

	* lang.c (java_tree_inlining_walk_subtrees): Remove.
	(LANG_HOOKS_TREE_INLINING_WALK_SUBTREES): Remove.

	cp/
	* cp-objcp-common.h (LANG_HOOKS_TREE_INLINING_WALK_SUBTREES):
	Remove define.
	* tree.h (cp_walk_tree): New define to walk_tree_1 with
	cp_walk_subtrees lh parameter.
	(cp_walk_tree_without_duplicates): New define to
	walk_tree_without_duplicates_1 with cp_walk_subtrees lh parameter.
	* tree.c (count_trees): Call
	cp_walk_tree_without_duplicates.
	(verify_stmt_tree): Call cp_walk_tree.
	(break_out_target_exprs): Likewise.
