- Fix recording of offsets of types in dependent PCHs.

- Stop reading in (and thus deserializing) every declaration in the TU when creating a dependent PCH.
- Switch the storage of a decl context's lexical declarations to a blob containing the IDs instead of a record. This is the only sane way of supporting update records later on.
