In vrp the problem is just that loop_optimizer_finalize (unnecessarily) calls
verify_flow_info. VRP already has TODO_cleanup_cfg and loop_optimizer_finalize
is the last thing done in execute_vrp, so the cfg will be properly cleaned up.
I'd say a fix could be if we had an argument to loop_optimizer_finalize whether
to do flow verification or not, and pass 0 here in vrp, perhaps other places
too.
