Normally, an unbound reference to a generic type within its own context is automatically bound to the identity generic arguments:
```
struct G<T> {
typealias TA = G // as if you wrote G<T>
}
```
Module selectors normally disable this kind of contextual behavior; make sure that this is not an exception.
To pipe the information needed to do this through the constraint solver, we extend FunctionRefInfo to remember whether a module selector was used.
