I'm working to make sure remaining diagnostics have coverage, at least the ones I'd previously added a TODO for. Note in particular that I couldn't figure out a repro for UnaryOperatorRequiresWhitespace; if you have one, I can add a test, but otherwise maybe it's actually unreachable due to being diagnosed through infix logic (or, maybe this'll let fuzzing tell me an example).
