Log message:
	* basic-block.h (PROP_*): Move constants from ...
	* flow.c: ... here.
	(compute_bb_for_insn): Free the array before reallocating.
	(update_life_info): New arg PROP_FLAGS; pass on to propagate_block.
	(allocate_reg_life_data): Reset all reg variables collected by
	propagate_block.
	(get_block_head_tail): Don't convert from bb to block.
	(get_bb_head_tail): New.  Update all callers of get_block_head_tail.
	(find_insn_reg_weight): Take block not bb.
	(schedule_block): Don't set block num for moved insns.
	(schedule_region): Don't update_life_info or find_insn_reg_weight.
	(schedule_insns): Do it here instead.
	* combine.c (combine_instructions): Invoke compute_bb_for_insn
	before update_life_info.
	* recog.c (split_all_insns, peephole2_optimize): Update for
	new arg to update_life_info.
	* rtlanal.c (remove_note): Cope with NULL note.
