      	Fix the dreaded export list bug
      With unfailing regularity I manage to get the following wrong:
      	module A(f) where 
      	  f = ...
      	module B(f) where
      	  import A(f)
      We must ensure that if A.f changes its type (etc) then B.hi
      gets changed, so that people who import B will get recompiled.
      There's a large comment with RnIfaces.mkImportInfo, and some
      reorganisation in Rename, with a few mainly cosmetic consequences
      in RnEnv.
      [Simon: I think this will fix the 'OccurAnal not recompiled' problem.]

      	Import more rules, and fix usage info
      1. A rule wasn't being slurped in that should have been.
      Reason: wordToWord32# was in the 'TypeEnv', because it's a primop,
      so the renamer thought it was already slurped in, which is true.
      But it forgot to use the TypeEnv as a source of gates when deciding
      which rules to pull in.  Result: a useful rule for the primop wasn't
      making it in.  Thanks to Marcin for isolating this one.
      2. RnIfaces.recordTypeEnvSlurp (was recordVSlurp) was blindly adding
      the name to the iVSlurp set, but the iVSlurp set is supposed to contain
      only "big" names (tycons, classes, and Ids that aren't data cons,
      class ops etc).  We need to get the big name from the thing.
      Mildly tiresomely, this means we have to keep the Class inside
      the TyCon derived from that class.   Hence updates to TyCon and Class.

      Add closure selection for heap profiling.  You can use
      -hc{cc_names}, -hd{descrs}, -hy{types}, -hm{mods} to restrict profiled
      closures to the specified sets.  Multiple restrictions are allowed.

      Add 'destruct :: Ptr a -> IO ()' method to class Storable. Thanks
      Wojciech Moczydlowski <khaliff@astercity.net> for the suggestion.
      It should free memory associated with the object (except the object
      pointer itself). A default definition does nothing, but will be
      non-trivial for some C structs.
      The canonical ForeignPtr finalizer for a malloced data object would be
      'destruct p >> free p'.

      	Nuke ClassContext
      This commit tidies up a long-standing inconsistency in GHC.
      The context of a class or instance decl used to be restricted
      to predicates of the form
      	C t1 .. tn
      	type ClassContext = [(Class,[Type])]
      but everywhere else in the compiler we used
      	type ThetaType = [PredType]
      where PredType can be any sort of constraint (= predicate).
      The inconsistency actually led to a crash, when compiling
      	class (?x::Int) => C a where {}
      I've tidied all this up by nuking ClassContext altogether, and using
      PredType throughout.  Lots of modified files, but all in
      more-or-less trivial ways.
      I've also added a check that the context of a class or instance
      decl doesn't include a non-inheritable predicate like (?x::Int).
      Other things
       * rename constructor 'Class' from type TypeRep.Pred to 'ClassP'
         (makes it easier to grep for)
       * rename constructor HsPClass  => HsClassP
      		      HsPIParam => HsIParam

      Some rearrangements that Simon & I have been working on recently:
          - CoreSat is now CorePrep, and is a general "prepare-for-code-
            generation" pass.  It does cloning, saturation of constructors &
            primops, A-normal form, and a couple of other minor fiddlings.
          - CoreTidy no longer does cloning, and minor fiddlings.  It doesn't
            need the unique supply any more, so that's removed.
          - CoreToStg now collects CafInfo and the list of CafRefs for each
            binding.  The SRT pass is much simpler now.
          - IdInfo now has a CgInfo field for "code generator info".  It currently
            contains arity (the actual code gen arity which affects the calling
            convention as opposed to the ArityInfo which is a measure of how
            many arguments the Id can be applied to before it does any work), and
            Previously we overloaded the ArityInfo field to contain both
            codegen arity and simplifier arity.  Things are cleaner now.
          - CgInfo is collected by CoreToStg, and passed back into CoreTidy in
            a loop.  The compiler will complain rather than going into a black
            hole if the CgInfo is pulled on too early.
          - Worker info in an interface file now comes with arity info attached.
            Previously the main arity info was overloaded for this purpose, but
            it lead to a few hacks in the compiler, this tidies things up somewhat.
      Bottom line: we removed several fragilities, and tidied up a number of
      things.  Code size should be smaller, but we'll see...
