Summary: There was an error being thrown from isDesirableToCommuteWithShift in some tests. This was tracked down to the method being called before legalisation, with an extended value type, not a machine value type. In the case I diagnosed, the error was only hit with an instruction sequence involving `i24`s in the add and shift. `i24` is not a Machine ValueType, it is instead an Extended ValueType which was causing the issue. I have added a test to cover this case, and fixed the error in the callback.
