Clear OLD_TO_SHARED slots in free memory after shrinking large objects. This CL now clear all slots outside of the object and not just from the next OS page boundary. Since we are already here also stop clearing OLD_TO_NEW and OLD_TO_OLD since they should already be cleared at this stage of the GC. Add DCHECKs that this always holds. We also don't need to iterate large code objects since we do not shrink such pages anyway.
