* bb-reorder.c (partition_hot_cold_basic_blocks): Do not
enter/exit cfglayout mode.
(pass_partition_block): Require it.
* combine.c (find_single_use, reg_dead_at_p): Use CFG.
(combine_instructions): Track basic blocks instead of labels.
(update_cfg_for_uncondjump): New.
(try_combine): Use it. Update jumps after rescanning.
(pass_combine): Require PROP_cfglayout.
* passes.c (pass_outof_cfg_layout_mode): Move after regmove.
