When an oop handle is released to OopStorage, we want to check that its contents has been cleared appropriately, honouring the general contract with OopStorage. This is currently done with a raw access checking for null. However, the raw contents in memory might not be 0, just because the logical value is null. In particular, generational ZGC will have some low order colour bits set. This CR aims to address that.
