Assuming you can get the oop map in stub, deoptimization could still be
delayed until the stub is exited. Is that considered a problem?

Actually I'm not even sure the loop synthesized from IR nodes is
feasible: what would the JVM state at the safepoint be given that
there's no actual java code for it? What would you deoptimize to if you
were to deoptimize?
