Instead of modifying the existing tests, could you add a dedicated test file for the change? Ideally covering strided load + stores, and regular loads + stores, with i32 index type (and maybe i128 index type) to cover the extend case as well?

That way we have a focused test for the index computations, and don't complicate the other tests
