When reading the generic parameters of a constrained protocol extension, cross-refencing an associated type would perform name lookup into the protocol extension itself, causing fatal recursion during deserialization. Fixed by avoiding additional deserialization when looking for an associated type. Fixes rdar://problem/20812303. Swift SVN r28228
