----------------
There's nothing we can diagnose about this without an instantiation (because
`S` could be an alias for a class having `V` as the injected-class-name).
It is, however, true that we don't diagnose this even with problematic
instantiations:
```
struct R { struct V; ~R(); };
struct QQ { using S = R; };
template <class T>
struct A { friend T::S::~V(); };
A<QQ> a;
```
