Add a new EvaluatedObject container

This container is used to store values that have already been evaluated.
For instance, 79d5a3a783cf0b5a729e4e467508e955a0cca55f added support
for inferring `tuple()` call arguments, but as a result, the `elts` of a `Tuple`
can be objects not *references*. As a result, `Tuple.elts` can contain class objects
rather than references (names) to class object. The `EvaluatedObject` helps with that,
as we still have to call `.infer()` (albeit a no-op) to grab the inferred value of an element.
