Represent the type as an `InstId` rather than as a `TypeId` to preserve how it was written and better support tracking its value in a generic. Add accessors to `Class` to get the base and adapted type to reduce code duplication, and add `TypeStore::GetObjectRepr` to make it easier to map from a type to its possibly-adapted object representation type. In passing, also move `GetIntTypeInfo` and `GetUnqualifiedType` into `TypeStore`. This fixes specifics of generic adapters to properly look at the specific adapted type, and also fixes importing of adapters. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
