  Log:
  Add a compacting garbage collector.
  
  It isn't enabled by default, as there are still a couple of problems:
  there's a fallback case I haven't implemented yet which means it will
  occasionally bomb out, and speed-wise it's quite a bit slower than the
  copying collector (about 1.8x slower).
  
  Until I can make it go faster, it'll only be useful when you're
  actually running low on real memory.
  
  '+RTS -c' to enable it.
  
  Oh, and I cleaned up a few things in the RTS while I was there, and
  fixed one or two possibly real bugs in the existing GC.
