E.g. obj_size(), adjust_obj_size(), scanned_block_is_obj() etc. I believe they are leftovers from CMS (not sure) but looks like they can be replaced by obj->size() or removed altogether. Also, the the related templated methods scan_and_forward(), scan_and_adjust_pointers() and scan_and_compact() can be directly and mechanically inlined into their callers. It makes the code more readable.
