Introduces transformations that insert

nodes in the ONNX graph at desired locations, which can either be a specified tensor (InsertIdentity
) or all top-level input/output tensors (InsertIdentityOnAllTopLevelIO
), as well as corresponding unit tests. This can be useful before calling transformations that do not gracefully handle edge cases where transformed tensors are top-level inputs or outputs.Original graph:
