Dafny: Since it's no longer true that all types support equality at run-time (in particular, codatatypes), Dafny needs to check this. In these changes, Dafny supports the "(==)" suffix to type parameters, infers that suffix in some cases, and enforces equality support in many places. Refinement and datatypes still need more attention in the Dafny implementation.
