(try_crossjump_bb): Exit loop after finding a fallthru edge. If something changed, set crossjumps_occured to true. (try_optimize_cfg): Clear crossjumps_occured at the beginning. Don't add/remove fake edges to exit here... (cleanup_cfg): ...but do it here, when crossjumping. Run a fast DCE when successful crossjumps occured in the latest iteration of try_optimize_cfg.
