Sanjay Patel 62da6ecea2 [InstCombine] substitute equivalent constant to reduce logic-of-icmps ...

(X == C) && (Y Pred1 X) --> (X == C) && (Y Pred1 C)
(X != C) || (Y Pred1 X) --> (X != C) || (Y Pred1 C)

This cooperates/overlaps with D78430, but it is a more general transform
that gets us most of the expected simplifications and several other
improvements.
