  Returns "not-equal" when value arg does not match an index in the typedArray
info: |
  Atomics.waitAsync( typedArray, index, value, timeout )

  1. Return DoWait(async, typedArray, index, value, timeout).

  DoWait ( mode, typedArray, index, value, timeout )

  16. Let w be ! AtomicLoad(typedArray, i).
  17. If v is not equal to w, then
    a. Perform LeaveCriticalSection(WL).
    b. If mode is sync, then
      i. Return the String "not-equal".
    c. Perform ! Call(capability.[[Resolve]], undefined, « "not-equal" »).
    d. Return promiseCapability.[[Promise]].
