> During Constant Propagation optimization, sometimes a node ends up being added to opToDelete
list more than once.
> Later in ConstantPropagate transform, we try to delete that operator multiple times,
which will cause SemanticException since the node has already been removed in an earlier pass.
> The data structure for storing opToDelete is List. We should use Set to avoid the problem.
