Now prints `C{...}` instead of `$anon`.
The self type as given (or implied for module classes) in the source. Also defined and updated for normal types, not just ClassInfo types. Common functionality between this and baseTypeWithArgs has been pulled into RefinedType#wrapIfMember.
Check that the self type of a class conforms to the self types of its parent classes.
- Abstract classes cannot be instantiated (exceptions: parent news and Java annotations) - Instantiateed class must conform to its self type.
Java compilation units should not be retained after typer, as no code will be generated for them. All we need from them are their symbols.
An error message might be suppressed because it contains internal code. But if it is the first one, we should still print it. Otherwise, we risk a scenario where we see "2 errors" but none is printed.

Alternative to #471. Add a separate phase that checks that abstract classes are not instantiated and that self types conform.
This is probably easier to understand than #471 because the flow is concentrated in one tree traversal instead of being indirectly established by dropping attachments and looking at them.
