  Gets constructor's `resolve` method once from zero to many invocations.

  5. Let result be PerformPromiseAny(iteratorRecord, C, promiseCapability).
  6. 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: PerformPromiseAny

  6. Let promiseResolve be ? Get(constructor, "resolve").
  7. If ! IsCallable(promiseResolve) is false, throw a TypeError exception.
  8. Repeat

    i. Let nextPromise be ? Call(promiseResolve, constructor, « nextValue »).
