I always suspected the overflow conversions were UB, but with gcc doing different things on arm, I thought it was about time to abandon those particular tests. What I was not expecting was for the return value of strcmp to be "UB" (in that there's no guarantee of the exact value, just < = > 0). Fortunately, nothing actually relies on the value of the op other than the tests, so modify the test to make the behavior well defined.
