Refactor spaces and add free list large object space

Added some more abstraction for spaces, we now have ContinuousSpaces and DiscontinousSpaces.

Added a free list version of large object space.

Performance should be better than the memory map version since we avoid creating more than
one memory map.

Added a cause for Gc which prints with the Gc message, dalvik has this as well.
