[ConstantRange] Handle wrapping range in binaryNot()

We don't need any special handling for wrapping ranges (or empty
ranges for that matter). The sub() call will already compute a
correct and precise range.

We only need to adjust the test expectation: We're now computing
an optimal result, rather than an unsigned envelope.
