Here are two optimizations for git-prune that we've been running at
GitHub for ages. No particular reason to share them now; they just
finally floated to the top of my todo pile. Do note that I rebased and
polished them (and the third one is brand new), so the concepts are
proven, but it's possible I introduced a new bug. ;)

  [1/3]: prune: lazily perform reachability traversal
  [2/3]: prune: use bitmaps for reachability traversal
  [3/3]: prune: check SEEN flag for reachability
