Seems like there are instances where adress spaces should be marked non-integral where they are not (for example, NVPTX see https://github.com/llvm/llvm-project/blob/c22828991e7ca7b99048761c078252e94403ba6e/llvm/lib/Target/NVPTX/NVPTXISelDAGToDAG.cpp#L765 , https://github.com/llvm/llvm-project/blob/c22828991e7ca7b99048761c078252e94403ba6e/llvm/lib/Target/NVPTX/NVPTXIntrinsics.td#L2395). In order for this to be legal, I'll need to find all such instances and correctly mark them as nonintegral.
