      Another big commit from Simon.  Actually, the last one
      didn't all go into the main trunk; because of a CVS glitch it
      ended up in the wrong branch.
      
      So this commit includes:
      
      * Scoped type variables
      * Warnings for unused variables should work now (they didn't before)
      * Simplifier improvements:
      	- Much better treatment of strict arguments
      	- Better treatment of bottoming Ids
      	- No need for w/w split for fns that are merely strict
      	- Fewer iterations needed, I hope
      * Less gratuitous renaming in interface files and abs C
      * OccName is a separate module, and is an abstract data type
      
      I think the whole Prelude and Exts libraries compile correctly.
      Something isn't quite right about typechecking existentials though.

      The Great Multi-Parameter Type Classes Merge.
      
      Notes from Simon (abridged):
      
      * Multi-parameter type classes are fully implemented.
      * Error messages from the type checker should be noticeably improved
      * Warnings for unused bindings (-fwarn-unused-names)
      * many other minor bug fixes.
      
      Internally there are the following changes
      
      * Removal of Haskell 1.2 compatibility.
      * Dramatic clean-up of the PprStyle stuff.
      * The type Type has been substantially changed.
      * The dictionary for each class is represented by a new
        data type for that purpose, rather than by a tuple.
