--- Comment #13 from Michael Nolan <mtnolan2640@gmail.com> ---
I've got something in decoder/selectable_int.py. It uses Power's bit ordering
so it should be good for the compiler but something to be aware of if it's used
anywhere else.

I'm not sure what to do about left shift and right shift. Should SelectableInt
(0x10, bits=8) << 4 equal SelectableInt(0x100, bits=12) or SelectableInt(0x00,
bits=8)

It's also unsigned only, I'm not sure how much that matters right now
