Comment(by jstolarek):

 I read paper about pointer tagging and things seem to be clearer now. I
 rewrote wiki page about [http://hackage.haskell.org/trac/ghc/ticket/6135
 PrimBool] from scratch. I think that now it defines the goal very clearly
 by giving code examples. There are also workarounds for the problem. If
 you guys could take a look and tell me if this makes sense it would be
 great.

 I failed to figure out a code example that would actually go faster using
 my workarounds. The ones I created have about 0,4% increase in
 performance, which is a negligible difference. I will be working on this.
