  -----------
  CogVM source as per VMMaker.oscogSPC-eem.2116

Temporary branch for SpurPlanningCompactor as default compactor.

Get the termination condition for copyAndUnmarkMobileObjects right.  Only exit
when finding a marked object beyond lastMobileObject.  Deal with coalescing free
space since this new variation may produce two adjacent free chunks when trying
to tread carefully past any pins.

Add and use oldSpaceObjectAfterUse in SpurPlanningCompactor to avoid the
overhead in objectAfter:.

Also see commit commit de43045c722a64b96e4503ad0942fce4cc89dca1 on the Cog
branch.
