This will allow us to skip setting the sticky bit of a parent task that calls @async in a finalizer, along with also allowing resource cleanup finalizers to use a finalizer-compatible implementation only when necessary.

The latest push fails on the added test, which I can reproduce in the REPL; @vtjnash any idea why this isn't working?

Is it to be expected that finalizer inlining may change the result of this function? If so, I think it would be good to at least document that fact
