To make this stick, I've disallowed direct use of that overload of CreateCall. I've left the Constant overloads available, but eventually we might want to consider fixing those, too, just to get all of this code out of the business of manually remembering to pass around attributes and calling conventions. The test changes reflect the fact that we weren't really setting attributes consistently at all, in this case on value witnesses.
