Generate super classes and overridden functions in proper scope

Such references require proper scope so that local symbols are bound.
Example:

```
fun <T> outer() {
    abstract class ALocal<S : T> {
        abstract fun bar()
    }

    class Local<S : T> : ALocal<S>() {
        override fun bar() {}
    }
}
```

Here local classes have type parameters with upper bounds depending on
function type parameters, and members overriding members in other local
classes.
