Given `FunctionType` is not specific to Java types i was reluctant to place Java-specific functionality on it. The current location is  temporary. `JavaType` has some functionality to mediate between `ClassDesc`, may be that is the right place to place mediate with other nominal descriptors, or maybe we need a specific place for this, resolution, and reasoning about specific types?

I wanted to wait until we improve the modeling of Java types, and rethink the naming/location of the (Java-specific) `*Desc` classes.
