I think this is the backwards direction. I think most passes consistently use - as a word separator, and the annoying cases do not

Sure I can go the other direction, I went this way because it was more consistent with relevant passes, but I agree that a dash is better overall.
Looks like I'd only have to update 43 tests for "functionattrs" -> "function-attrs".
