This is required to get auto linking to work when there is no explicit import in the main file.  Also resolve a FIXME to rename 'ExternalDefinitions’, since that is only one of the things that need eager deserialization. The new name is 'EagerlyDeserializedDecls'.  The corresponding AST bitcode is also renamed.
