  Promise is rejected when the "resolve" capability returns an abrupt
  completion.

  3. Let promiseCapability be ? NewPromiseCapability(C).
  ...
  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).
  8. Return Completion(result).

  Runtime Semantics: PerformPromiseAllSettled

  6. Repeat
    ...
    d. If next is false, then
      ...
      iii. If remainingElementsCount.[[Value]] is 0, then
        1. Let valuesArray be CreateArrayFromList(values).
        2. Perform ? Call(resultCapability.[[Resolve]], undefined, « valuesArray »).


  IfAbruptRejectPromise

  1. IfAbruptRejectPromise(value, capability).
