[InstCombine] Fold (X==Z) ? (Y==Z) : (!(Y==Z) && X==Y) --> X==Y (#108619)

This corresponds to the canonicalized form of some logic that was
seen in Swift-generated code for comparing optional point

[InstCombine] Fold (X==Z) ? (Y==Z) : (!(Y==Z) && X==Y) --> X==Y (#108619)

This corresponds to the canonicalized form of some logic that was
seen in Swift-generated code for comparing optional pointers:
`(X==Z || Y==Z) ? (X==Z && Y==Z) : X==Y --> X==Y`
where `Z` was the constant `0`.
