* 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.
