      - Be a bit more accurate about +RTS -H<size>, now we attempt to estimate
        the amount of memory that will be needed at the next GC based on
        the amount of promotion going on, and adjust the size of the allocation
        area appropriately.
      - tidy up, move some stuff into Storage.c.

      Use the +RTS -H<size> flag as a "suggestion" to the garbage collector
      to use that much heap.  If you have plenty of memory, then saying
      +RTS -H<large> will really help GC times.

      Finally!  This commits the ongoing saga of Simon's hygiene sweep
      a) The 'unused variable' warnings from the renamer work.  
      b) Better error messages here and there, esp type checker
      c) Fixities for Haskell 98 (maybe I'd done that before)
      d) Lazy reporting of name clashes for Haskell 98 (ditto)
      a) type OccName has its own module.  OccNames are represented
         by a single FastString, not three as in the last round.  This
         string is held in Z-encoded form; a decoding function decodes
         for printing in user error messages.  There's a nice tight
         encoding for (,,,,,,,,,,,,,,,,,,,,,,,,,,,,,)
      b) type Module is a proper ADT, in module OccName
      c) type RdrName is a proper ADT, in its own module
      d) type Name has a new, somwhat tidier, representation
      e) much grunting in the renamer to get Provenances right.
         This makes error messages look better (no spurious qualifiers)

      The BLACKHOLEs created when entering a CAF for the first time are now
      CAF_BLACKHOLES, distinguishing them from the blackholes created by
      lazy blackholing.
      This enables the lazy blackholing algorithm to be optimised by not
      blackholing a section of stack that has already been traversed.

      - BLACKHOLE_BQ is a mutable object, because new threads get added to
        its blocking_queue field.  Hence add a mut_link field and treat it
        as mutable in the garbage collector.
      - Change StgBlackHole to StgBlockingQueue while I'm at it.
      - Optimise evacuation of black holes: don't copy the padding
        words, just skip over them.
      - Several garbage collection fixes.
      - Improve sanity checking: now the older generations are fully checked
        at each GC.

      - do MVARs properly.
      - skip over slop between objects, by searching for the first info pointer.
        this works for slop created by updates, for example.

      'Native' Wni32 implementation of getMBlock(). Also added a Win32 impl.
      of freeMBlock() in case that ever should become useful.

      - Add new object BLACKHOLE_BQ: now a BLACKHOLE is defined as having an
        empty blocking queue, and the first time a thread blocks on a BLACKHOLE
        it is changed into a BLACKHOLE_BQ.
      - Remove UPD_INPLACE1 and replace it with UPD_IND in the two places it
        was used.  UPD_INPLACE1 wouldn't have worked in a generational setting.

      Remove 'const' modifier from static closure declarations.  Static
      closures are meant to live in R/W data space.

      Forgot to commit this before Christmas...on Win32 platforms use
      VirtualAlloc() instead CreateFileMapping()&friends to ask for
      mega-blocks from the OS. Windows 95-friendlier.
