why do you have to remove this check? it should still hold?

Object can now be in ToSpace, FromSpace, or even old space. Created a new DCHECK
which precisely checks when it should be where.

   if (!FLAG_allocation_site_pretenuring ||
       !AllocationSite::CanTrack(object->map()->instance_type()))
     return;
