It is legal, but not generated by any SPIR-V producer: an OpAccessChain with no indexes. This is essentially just a copy of the pointer. I have decided to treat it like an OpCopyObject. In CheckUses, we return that it is not okay. When looking at this I realized that we had code in GetUsedComponents that cannot be reached. If there is a use in an OpCopyObject the it will not call GetUsedComponents. I removed that dead code. Fixes https://crbug.com/918311.
