	* jump.c (reset_insn_reg_label_operand_notes): New function,
	split out from ...
	(init_label_info): ... here.  Reset LABEL_NUSES in cfglayout mode.
	* cfgcleanup.c (delete_dead_jump_tables_between): New function,
	split out from ...
	(delete_dead_jumptables): ... here.  Handle cfglayout mode.
	(cleanup_cfg): Delete dead jump tables in cfglayout mode if an
	expensive CFG cleanup is called for.
	* cfgrtl.c (fixup_reorder_chain): Remove BARRIERs from fallthru paths.
	(cfg_layout_finalize): Delete dead jump tables before re-building
	the insns chain.
	* ira.c (ira): Rebuild jump labels *after* deleting unreachable
	basic blocks, not before.
	* loop-init.c (rtl_loop_done): Call for an expensive CFG cleanup.

	* modulo-sched.c (sms_schedule): Do not look for BARRIERs in the
	insns chain of a scheduling extended basic block, they cannot appear
	there in cfglayout mode.
