Is this really the most direct way to get %AsyncIteratorPrototype%?

Yeah, I think you have to go three levels along the prototype chain
from what those give you to get to `%AsyncIteratorPrototype%`:
http://jsfiddle.net/dbh9j7av/ Which makes sense (proto on the gen
object is the async generator function's `.prototype`; its prototype
is `AsyncGeneratorFunction.prototype`, and its prototype is
`%AsynIteratorPrototype%`). But again, maybe I'm missing something.
(If not, I probably need to send a PR to tc39 / test262.)
