As KVM now strongly relies on accurately handling the RES0/RES1 bits
on a number of paths, add a compile-time checker that will blow in
the face of the innocent bystander, should they try to sneak in an
update that changes any of these RES0/RES1 fields.

It is expected that such an update will come with the relevant
KVM update if needed.
