Dead code detection

[Simon Peyton-Jones]

GHC will report unused bindings (-fwarn-unused-binds)
but only within a module.  If it's exported, GHC doesn't help you.

I'm sure GHC itself has plenty of dead code that only a global analysis
can spot!

GHC's interface file for a module reports all the imported things that
the module
depends on. So the raw material for a global analyser is in place.
