  Log Message:
  -----------
  [mlir][bufferize] Implement BufferizableOpInterface for tensor.empty

The op is not bufferizable but should be analyzable (for `EliminateEmptyTensors`, which uses the bufferization infrastructure).

Also improve debugging functionality and error messages.

Also adds a missing pass to the sparse pipeline. (tensor.empty should be replaced with bufferization.alloc_tensor, but it sometimes used to work without depending on how the tensor.empty is used. Now we always fail explicitly.)
