1. Some special-case code in find-all-refs is no longer relevant.
2. Using the real symbol gives names to more class expressions, so I
made the expression more complex to keep the class truly anonymous in
goToImplementationInterface_07. The quick info display also changes,
from
```
(anonymous local class)
```
to
```
(local class) (Anonymous class)
```
This is more consistent internally and externally, so I think it's a
good change.
And accept baselines for later inspection.
One fourslash test changes, indicating that quick info relied on
getTypeAtLocation not returning anything for class expressions to
distinguish named from anonymous class expressions. This predicate will
have to be improved.
