  * Make SpecConstr more informative output when there are too many specialisations
  Ignore-this: 9526c38858763f2378a5184ed73df32f
  
  It now says something like
  
    SpecConstr
      Function `happyDoAction'
        has 17 call pattterns, but the limit is 3
      Use -fspec-constr-count=n to set the bound
      Use -dppr-debug to see specialisations
  
  Previously it just silently did no specialisation

    M ./compiler/specialise/SpecConstr.lhs -7 +11
