Bump pointer space only collection.
Add a mode of collection that collects only the bump pointer spaces,
as opposed to the whole heap. It's disabled behind a flag.
TODO: It still scans the entire non-moving space to look for
inter-space references. Use a card table like technique to limit the
scope of scanning and speed it up.
