We already have a data dependency from CentralFreeList::object_size_ to determine whether we are in a small object (list-ful) or large object (bitmap-ful) Span, so this merely replaces it. It eliminates the conditional logic driven off of that load and turns it into a single load from the Span. PiperOrigin-RevId: 942682828
