for signed overflowing remainder, delay comparing lhs with MIN
Since the wrapped remainder is going to be 0 for all cases when the rhs is -1, there is no need to divide in this case. Comparing the lhs with MIN is only done for the overflow bool. In particular, this results in better code generation for wrapping remainder, which discards the overflow bool completely.
