runtime: use innermost frame's func name for async preemption check 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.
