Add Z.div_mod_to_quot_rem tactic, put it in zify
The various (micr)omega tactics now support `Z.div` and `Z.modulo`.
I briefly looked into supporting `Nat.div` and `Nat.modulo`, but the
conversions between `Z.div` and `Nat.div` are defined in `ZArith.Zdiv`,
which depends on `Omega`, which depends on `PreOmega`, which is where
`zify` is defined.
