Right, underlyingly what's being tested is going to be different. But 
eventually I imagine we'll want *some* manner of tests for int 
instructions in sm1, so it probably makes sense to reuse these. 
(Assuming they behave sanely, that is. No need to bend over backwards to 
accommodate both sm1 and sm4 in the same test unit.)
