Include call-pattern specialisation in the Simplifier, for a radical change

I'm not keen on this * The Simplifier and `SpecConstr` are both very complex passes. Combining them would be ... difficult. * `SpecConstr` relies on a pretty elaborate form of occurrence analysis, which I'm not sure we'd want to replicated in the simplifier. Let's be really sure that nothing else will work first. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/855#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
