[frontend] When serializing compiled expression proc, clone type params first.

If there are circular references between type parameters and types in the bounds,
currently serialization leaves original type parameters unchanged, which results
in failures to serialize compiled expression procedure.

This CL makes sure to clone all type parameters first, then passes map
with old-to-new type parameters to CloneVisitor.
