#6289 absentmindedly added fields in more places, and this is undoing that plus further fixes. This does some cleanup of types with relation to singletons. For `TypeType` and `ErrorInst`, they're always complete due to a `SetComplete` call in `file.cpp`. For `CppVoidType`, it's intended to be incomplete by construction, and so a `TypeId` should be okay. The intent though on not generally providing these had been that `GetSingletonType` needs to be called to get a type to be marked as complete. In the case of `AutoType`, removing `TypeId`does change a small printing detail. I think that's old legacy that's just been carried forward. Otherwise, for both `InstType` and `AutoType`, I've added `GetSingletonType` calls where they were used in order to ensure completeness is applied correctly. These calls cause small SemIR permutations. This causes `AutoType` to be seen by lowering, so I'm adding a placeholder for it. Also merging two functions that look like they're identical in intent -- not sure why they're separate. --------- Co-authored-by: Dana Jansens <danakj@orodu.net>
