Yes, `-9223372036854775808` is a sentinel for `kDynamic`. I forgot how `allocateTensorForShapedValue` is implemented, but it may query an interface to reify the result shape.

I'd be curious where `arith.constant -9223372036854775808` is generated. Looks like it's not used anywhere, so that's good. But the fact that we even generate this could indicate a bug.
