The error is usually attached to the transform op. You can add a note that points to the payload op.

E.g.:
```c++
DiagnosedSilenceableFailure diag = emitSilenceableError()
                                   << "cannot lower to transpose + collapse + extract";
diag.attachNote(target->getLoc()) << "target payload op";
return diag;
```
