Carl Lerche 032b39487c sync: add spin_loop_hint to atomic waker (#1608) ...

The algorithm backing `AtomicWaker` effectively uses a spin lock backed
by notifying & yielding the current task. This adds a `spin_lock_hint`
annotation to cover this case.

While, in practice, the omission of `spin_lock_hint` would not cause
problems, there are platforms that do not handle spin locks very well
and could enter a deadlock in pathological cases.
