The idea is to aggressively outline more, because for some applications most of the code is cold, getting profile information is difficult and goal is to improve startup time. non-determinism is not required, it will be great to have  a deterministic heuristic. I'm open to ideas.

There is some heuristic in the static-profile analysis but it does not outline as much.
