Sanjay Patel 6382ee0e42 [InstCombine] fix profitability equation for max-of-nots transform ...

As the test change shows, we can increase the critical path by adding
a 'not' instruction, so make sure that we're actually removing an
instruction if we do this transform.

This transform could also cause us to miss folds of min/max pairs.
