Not sure I get it. I think this same builder code is reused both for downcalls and upcalls; but we don't want to do the
transformation for upcalls. So at the very least we'd need to pass a boolean to turn the transformation on/off. If we
go down this path, then I guess TypeTranslator could be reverted back to what it was - is that what you are suggesting?
