An interesting case that [came

involves dependent return type.
I think we should not be showing this error if there is a dependent return type.
```cpp
template <class T, class R = void> R foo(const T& t [[clang::lifetimebound]]);
foo<int>(1);
const int& r = foo<int, int>(1);
```
There is no way to fix this for one instantiation and not for the other so we
should be accepting these.
Can you also add test involving tempates with and without dependent return
types.
