The only entities specific to the K- model are `KLocalFunction` and `KLocalTypeVariable`. I've copied these both (as is) to the J- model.
The only thing we "lose" here is the calls to `checkFamily` in `kernel/element_map_impl.dart`. Given how interchangable the 2 models were, this wasn't adding much value anyway.
Since there is still a distinction between the K- environment and J- environment, we can now think of that conversion as being between a `J` and `J'` environment where the semantics are slightly different (e.g. `J'` has closure conversion applied).
Using the same model also makes it easier to have more intermediate states of the `J` model. For example, we might keep around the `JLocalFunction` nodes until SSA and do closure conversion at that point instead.
