	* tree-cfg.c (tree_make_forwarder_block): Use
	flush_pending_stmts.
	* tree-flow.h: Add a prototype for flush_pending_stmts.
	* tree-ssa-loop-manip.c (tree_duplicate_loop_to_header_edge):
	Use flush_pending_stmts.
	(lv_update_pending_stmts): Remove.
	(tree_ssa_loop_version): Use flush_pending_stmts instead of
	lv_update_pending_stmts.
	* tree-ssa.c (flush_pending_stmts): New.
