    Remove from `base` obsolete CPP for `integer-gmp`
    
      * `GHC.Natural` now exports the same functions (regardless of integer backend)
      * remove unnecessary CPP around instances
      * remove the 'OPTIMISE_INTEGER_GCD_LCM' flag - almost all of those optimizations
        now work regardless of which integer backend is used
    
    Note that some CPP still remains for situations where there are backend-specific
    optimization hacks (like a more efficient GMP-only `gcd` for `Int#` and `Word#`).
