Prepare beam_utils to run again after beam_split
beam_utils:live_opt/1 is currently only run early (from beam_block). Prepare it to be run after beam_split when instructions with failure labels have been taken out of blocks. While we are it, also improve check_liveness/3. That will improve the optimizations in beam_record (replacing tuple matching instructions with an is_tagged_tuple instruction).
