<summary>Changes</summary>

This is a follow-up to 8c2bff1ab929 which lazy-initialized the diagnostic and removed the need to dynamically abandon() an InFlightDiagnostic. This further simplifies the code to not needed to return a reference to an InFlightDiagnostic and instead eagerly emit errors.

Also use `emitError` as name instead of `getDiag` which seems more explicit and in-line with the common usage.
