Try to be more robust against un-checked types during lowering, etc.

- Try to handle `ErrorType` gracefully when computing type layouts

- When outputting a `TypeExp`, if the type part is errorneous (or missing), try to use the expression part

- Make sure to lower the expressions side of a `TypeExp` during lowering
