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.
