Checking whether two KnownBits are the same is somewhat common, mainly in test code.

I don't think there is a lot of room for confusion with "determine what the KnownBits for an icmp eq would be", as that has a different result type (this is the `eq()` method implements, which returns `Optional<bool>`).
