Sorry about this, but it seems I was wrong. If we just call setDesc
then the MachineOperands are still tied and the verifier gets confused
(leading to at least one Green Dragon failure). I couldn't find a
simple way to untie them so I've just reverted this in r309962.

I don't think there's any need for a followup to reapply this, it was
a peephole change anyway really.

Cheers.

Tim.
