This is something I noticed working on https://github.com/carbon-language/carbon-lang/pull/3884; I think we have more functions named Diagnose* at present than Emit* or Report*, so just trying to consolidate. Note a couple Diagnose* functions do a little more validation, but maybe those should actually be renamed away (zygoloid had mentioned wanting to generally split out diagnostics to their own function, and then we'd have it be a more common pattern).
