* failing test
* cleaner failing tests
* assign and read of same slice shouldn't create copies
* err in the changes
* shrink with no overlapping regions in dest is fine
The memory planner was suballocating BUFFERs created during JIT capture that are still referenced by external lazy tensor graphs, like the .grad tensors assigned by backward(). The replay then only writes the arena slices, so realizing such a tensor after the call reads freshly allocated memory and silently returns zeros. Hold every BUFFER reachable from a live Tensor instead of only the parameters of the return value; true internals are still planned. Fixes#16571.
