    ghc-bignum is a newer package that aims to replace the legacy
    integer-simple and integer-gmp packages.
    
    * it supports several backends. In particular GMP is still supported and
      most of the code from integer-gmp has been merged in the "gmp"
      backend.
    
    * the pure Haskell "native" backend is new and is much faster than the
      previous pure Haskell implementation provided by integer-simple
    
    * new backends are easier to write because they only have to provide a
      few well defined functions. All the other code is common to all
      backends. In particular they all share the efficient small/big number
      distinction previously used only in integer-gmp.
    
    * backends can all be tested against the "native" backend with a simple
      Cabal flag. Backends are only allowed to differ in performance, their
      results should be the same.
    
    * Add `integer-gmp` compat package: provide some pattern synonyms and
      function aliases for those in `ghc-bignum`. It is intended to avoid
      breaking packages that depend o...
