PR debug/45136
PR debug/45130
* haifa-sched.c (get_ebb_head_tail): Move notes across boundary
debug insns.
(no_real_insns_p, schedule_block, set_priorities): Drop special
treatment of boundary debug insns.
* sched-deps.c (sd_init_insn, sd_finish_insn): Don't mark debug
insns.
* sched-ebb.c (schedule_ebbs): Don't skip debug insns.
* sched-int.h (DEBUG_INSN_SCHED_P): Remove.
(BOUNDARY_DEBUG_INSN_P): Likewise.
(SCHEDULE_DEBUG_INSN_P): Likewise.
* sched-rgn.c (init_ready_list): Drop special treatment of
boundary debug insns.
* final.c (rest_of_clean-state): Clear notes' BB.
