Comment(by jstolarek):

 I'm looking at the diff and I don't think that I could possibly split it
 into smaller changes. The problem is that once you change one of the
 primops to return `Int#`, you have to change them all because they all
 fall into the same Compare category. And then you need to fix deriving of
 Eq and Ord. These are the smallest changes I was able to make and have the
 code compile.
