I guess for empty bbs with no successor where the predecessor ends in an
conditional jump without side-effects try_optimize_cfg can't do just
delete_basic_block, but needs to call some function to actually adjust the
conditional jump into unconditional. Perhaps try_redirect_by_replacing_jump or
something similar.
