Log:
* sel-sched-ir.c (return_nop_to_pool): Add full_tidying argument.
Adjust callers.
(setup_id_for_insn): Choose suitable type for debug insns.
(tidy_control_flow): Skip debug insns.
(sel_remove_insn): Remove debug insn from av_set of its BB.
(sel_estimate_number_of_insns): Don't count debug insns.
(create_insn_rtx_from_pattern): Handle debug insns.
(create_copy_of_insn_rtx): Likewise.
* sel-sched.c (moving_insn_crates_bookkeeping_block_p): New.
(moveup_expr): Handle debug insns.
(moveup_expr_cached): Don't use the cache for debug insns that are
heads of blocks.
(compute_av_set_inside_bb): Skip debug insns.
(sel_rank_for_schedule): Move debug insns first.  Remove redundant
sets of tmp_insn and tmp2_insn.
(find_block_for_bookkeeping): Introduce lax mode.
(create_block_for_bookkeeping): When splitting a block with debug
insns only, emulate the behavior of splitting its single successor.
(find_place_for_bookkeeping): Don't use debug-only blocks for
bookkeeping.
(generate_bookkeeping_insn): Accept not finding a place to insert.
(remove_temp_moveops_nops): Add full_tidying argument.
Adjust callers.
(prepare_place_to_insert): Don't choose the normal place to insert
if we're looking at a list of debug insns.
(advance_state_on_fence): Don't start a cycle at a debug insn.
(update_boundaries): Handle debug insns.  Update fence insn.
(schedule_expr_on_boundary): Don't fully-tidy after debug insn.
(fill_insns): Don't stop after moving a debug insns to the end of
a basic block.
(track_scheduled_insns_and_blocks): Don't count debug insns.
(need_nop_to_preserve_insn_bb): Handle debug insns.  Split out of...
(remove_insn_from_stream): ... this.
(fur_orig_expr_not_found): Handle debug insns.
(code_motion_path_driver): Fix return type.
* sched-deps.c (sched_analyze_insn): Honor readonly flag.  Don't add
pending memory flush deps for jumps in sel-sched.
* sel-sched-ir.h (sel_bb_empty_or_nop_p): New.
(get_all_loops_exit, _eligible_successor_edge_p): Use it.
(return_nop_to_pool): Update prototype.
