8.2.3.28 Tuple.prototype.toReversed ( )
When the toReversed method is called, the following steps are taken:
1. Let T be ? thisTupleValue(this value).
2. Let oldList be a new List containing the elements of T.[[Sequence]].
3. Let newList be a new empty List.
4. Repeat, while oldList is not empty,
a. Remove the last element from oldList, and let E be the value of the element.
b. Append E to the end of List newList.
5. Return a new Tuple value whose [[Sequence]] is newList.
