This scenario was uncovered in a downstream test that failed with a previous snapshot of torch-mlir. See https://github.com/cruise-automation/mlir-tcp/actions/runs/8605480116/job/23581829102?pr=65.

    raise NotImplementedError(
NotImplementedError: Could not deduce type from value info: tensor_meta=None, val=s1, sparsity=None

It seems to have resolved on current HEAD. Adding this test to ensure coverage in the future.
