Primop changes in GHC 7.8
TODO Austin, this page is yours to prepare. Please do mention isTrue# and encourage people to use it for converting Int# to Bool (if they need to do such a conversion that is). Deatils are here (second bullet) and in Note [Optimizing isTrue#] (in ghc-prim).
If you're interested in technical details behind this change, see this page.
