Thank you for the explanation, that was helpful!
Perhaps dumb question: would it make more sense to have the cast checks in
`isSameComparisonOperand()` single-step through the casts to find matching
ones? Because it seems a bit odd that inserting a Noop cast in one node but not
the other would mean they're automatically different comparison operands.
