[mlir][IR] Improve error message when return type could not be inferred

Print an error such as the following one before terminating program execution.
```
mlir/test/Dialect/SparseTensor/convert_dense2sparse.mlir:26:8: remark: location of new op
  %0 = sparse_tensor.convert %arg0 : tensor<?xi32> to tensor<?xi32, #SparseVector>
       ^
LLVM ERROR: Failed to infer result type(s):
"sparse_tensor.positions"(...) {} : (index) -> ( ??? )

(stack trace follows)
```
