  Log Message:
  -----------
  [Attributor] Add helper to change an instruction to `unreachable` inst

Summary: Calling `changeToUnreachable` in `manifest` from different places might cause really unpredictable problems. As other deleting functions are doing, we need to change these instructions after all `manifest`.
