Doug Gregor d4fca2cc8b [Serialization] Lazily form context types for deserialized patterns. ...

When a pattern within a type context is serialized, serialize its
interface type (not its contextual type). When deserializing, record
the interface type and keep a side table of the associated
DeclContext, so that we can lazily map to the contextual type on first
access. This is designed to break recursion when we change the way
archetypes and generic environments are serialized.
