This is part two of the implementation (part 1: heuristics in NCI code
to call the runtime profiler, part 2: heuristics in the runtime
profiler to mark the function for optimization, part 3: the final
part, recognizing and acting upon the marked function).

The runtime profiler heuristics added here remain very similar to what
we have for ignition, except that we now inspect optimized frames with
NCI code, and that we (currently) do not OSR from NCI to TF.
