  6. Let result be PerformPromiseAllSettled(iteratorRecord, C, promiseCapability).
  7. If result is an abrupt completion, then
    a. If iteratorRecord.[[Done]] is false, set result to IteratorClose(iteratorRecord, result).
    b. IfAbruptRejectPromise(result, promiseCapability).

  Runtime Semantics: PerformPromiseAllSettled

  6. Repeat
    ...
    i. Let nextPromise be ? Invoke(constructor, "resolve", « nextValue »).
