Original issue's description:
> [es6] Object.getPrototypeOf should work with values
>
> The final spec for Object.getPrototypeOf calls ToObject on the
> parameter, which means that it should only throw for null and
> undefined. For other non object values the prototype of the wrapper
> should be used.
