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 »).
