                         TcIface.lhs 
  Log:
  Get rid of DiscardedInfo, and fix a Ghci bug at the same time.
  
  The new story is this:
  
  - We always read the whole interface file, as it exists on disk,
    not dropping pragmas or anything.
  
  - We compare that from-the-disk copy with the new version before
    writing the new interface file.
  
  - We drop the pragmas
    a) Before loading the interface payload into the declaration pools
    b) In the no-need-to-recompile case, before typechecking the
  	interface decls.  Omitting this was the previous bug.
