We don't asynchronously preempt if we are in the runtime. We do this by checking the function name. However, it failed to take inlining into account. If a runtime function gets inlined into a non-runtime function, it can be preempted, and bad things can happen. One instance of this is dounlockOSThread inlined into UnlockOSThread which is in turn inlined into a non-runtime function. Fix this by using the innermost frame's function name.
