[X86] Correct a typo I made in combineToExtendCMOV recently.

We're accidentally checking that the same node is a constant twice instead of checking the other node.

This isn't a functional problem since we didn't do anything below that explicitly requires constants. It just means we may have introduced a sign_extend or zero_extend that won't fold out.
