* basic-block.h (BB_REACHABLE): Renumber.
(BB_DIRTY, BB_NEW): New flags.
(clear_bb_flags): Declare.
(update_life_info_in_dirty_blocks): Declare.
* cfg.c (clear_bb_flags): New function.
* cfgrtl.c (create_basic_block_structure): Set flags to BB_NEW.
* emit-rtl.c (add_insn_after, add_insn_before, remove_insn,
reorder_insns, emit_insn_after): Mark block as dirty.
* flow.c (update_life_info): Fix clearing of PROP_LOG_LINKS.
(update_life_info_in_dirty_blocks): New function.
* recog.c (apply_change_group): Dirtify block.
* cse.c (cse_insn): Reorder emitting of jump insn to keep
cfg consistent.
* gcse.c (delete_null_pointer_checks): Likewise.
* toplev.c (dump_file_index): Move cse2 after bp,
add DFI_null
(dump_file_info): Similary.
(rest_of_compilation): Avoid most of CFG rebuilds;
do first if converision after null pointer checks, do cse2
after branch prediction; avoid full liveness rebuild after
initializing subregs.
* invoke.texi (-d options): Document -du, renumber.
* cfgcleanup.c (bb_flags): Remove BB_UPDATE_LIFE.
(notice_new_block): Do not set BB_UPDATE_LIFE.
(try_forward_edges, merge_blocks_move_predecessor_nojumps,
merge_blocks_move_successor_nojumps, merge_blocks,
try_crossjump_to_edge): Likewise.
(try_optimize_cfg): Likewise; use update_life_info_in_dirty_blocks.
* cfgrtl.c (merge_blocks_nomove): Copy b's flags to a.
* ifcvt.c (SET_UPDATE_LIFE, UPDATE_LIFE): Kill.
(merge_of_block): Do not use life_data_ok.
(find_if_case_1): Do not use SET_UPDATE_LIFE.
(if_convert): Use BB_DIRTY mechanizm to update life.
* lcm.c (optimize_mode_switching): Update
update_life_info_in_dirty_blocks
