Sanjay Patel 9a14d9afe1 [InstCombine] enhance freelyNegateValue() by handling 'not'
This patch extends D77230. If we have a 'not' instruction inside a
negated expression, we can ignore extra uses of that op because the
negation has a one-to-one replacement: negate becomes increment.

Alive2 examples of the test cases:
