What happened
Add an include_fallback option to custom-op autotuning and thread it through both standard and range-based lowering. It defaults to True , preserving the existing behavior of including the custom op itself as an external fallback choice. Callers can set it to False when the custom op is used only as an autotuning/rewriting vehicle and should not itself be emitted as a candidate. This is used by facebookexperimental/…
