Timothy Flynn 7ee415a7c2 LibJS: Directly indicate when the IteratorHelper generator is complete ...

Our existing implementation was checking if the generator step result
was `undefined` to indicate that the generator is complete. This is
not sufficient for an upcoming implementation of Iterator.concat, where
`undefined` is used as an incomplete iteration result.

Instead, let's have the Iterator prototype return an IterationResult to
explicitly indicate its completeness. As a result, the prototype also
looks more like the spec now.
