Richard Smith 71aa4a45be Distinguish between name IDs and string IDs in the type system. (#3341)
Add a `NameId` that is effectively just a wrapper around a `StringId`,
with
some additional predefined values for names that don't correspond to
strings, such as the name of `self` or the function's return slot.
