        Description

        Similar to how object allocations should be owned by the GC, so does TLAB dummy object 'allocation'. TLABs and PLABs are filling their remaining blocks with dummy objects. GCs like Shenandoah might need a slightly differet layout for this, and therefore we need an abstraction.
