I think adding (another) by-name ordering for matchables is not a good idea. Renaming things should not cause functional changes. I would rather welcome introducing proper means of communicating the intention/expectation of some matchables to be tried before others instead of complicating the situation further by employing ad-hoc workarounds.

Did you try `HasPositionOrder` of the `Instruction` TableGen class?
