    Re-implement `powModInteger`  (#9281)
    
    This also exposes the following type-specialised modular exponentiation
    variants of `powModInteger` useful for implementing a `powModNatural`
    operation.
    
      powModBigNat     :: BigNat -> BigNat -> BigNat -> BigNat
      powModBigNatWord :: BigNat -> BigNat -> Word#  -> Word#
      powModWord       :: Word#  -> Word#  -> Word#  -> Word#
    
    `powModInteger` has been available since `integer-gmp-0.5.1`
    (added via 4d516855241b70eb687d95e3c121428de885e83e)
