Re-engineer the derived Ord instance generation code (fix Trac #4019)

  
As well as fixing #4019, I rejigged the way that Ord instances are
generated, which should make them faster in general.  See the 
Note [Generating Ord instances].

I tried to measure the performance difference from this change, but
the #4019 fix only removes one conditional branch per iteration, and
I couldn't measure a consistent improvement.  But still, tihs is
better than before.
