Cherry Zhang dcdee153cd 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.
