"this" pointer for any subclass of User, you could static_cast it to
User* and then reinterpret_cast that to Use* to get the end of the
operand list. This isn't a safe assumption in general, because the

OperandTraits classes take an extra template parameter, which is the
subclass of User. This is groundwork for PR889.
