// automatically generated by the ClusterScopingPass when auto_jit is on.  As
  // such, we respect _XlaScope only when auto_jit is off, while respecting
  // _XlaInternalScope only when auto_jit is on.
  //
  // We may want to restrict the _XlaScope behavior to require all nodes marked
  // with _XlaCompile=true to also have a _XlaScope property set (and raise an
  // error otherwise); but for now we don't do this.
