Add missing zify class instances
Add missing zify class instances for `Pos.pred_double`, `Pos.pred_N`,
`Pos.of_nat`, `Pos.add_carry`, `Pos.pow`, `Pos.square`, `Z.pow`, `Z.double`,
`Z.pred_double`, `Z.succ_double`, `Z.square`, `Z.div2`, `Z.quot2`, `isZero`, and
`isLeZero`. Instances for `isZero` and `isLeZero` are useful to provide new
zify instances by using Micromega tactics.
