Multiple comments above ([example](https://github.com/llvm/llvm-project/pull/68894#issuecomment-1765549641)) have suggested using block arguments. We have recently added a new token type to MLIR. Another approach that won't regress CSE/DCE/... would be to add a new token block argument to `linalg.generic`, and let `linalg.index` take that token as an operand. That way, `linalg.index` could remain `Pure`.
