description: throw rejects promise when `this` value not an object
info: |
  AsyncGenerator.prototype.throw ( exception )
  1. Let generator be the this value.
  2. Let completion be Completion{[[Type]]: throw, [[Value]]: exception,
     [[Target]]: empty}.
  3. Return ! AsyncGeneratorEnqueue(generator, completion).

  AsyncGeneratorEnqueue ( generator, completion )
  ...
  3. If Type(generator) is not Object, or if generator does not have an
     [[AsyncGeneratorState]] internal slot, then
    a. Let badGeneratorError be a newly created TypeError object.
    b. Perform ! Call(promiseCapability.[[Reject]], undefined, « badGeneratorError »).
    c. Return promiseCapability.[[Promise]].
