The deprecated class NonLocalReturns.ReturnThrowable acquired a new base type `caps.Control` in 3.8. That was a mistake. Later versions of the capture checker reject that inheritance since `ReturnThrowable` is an exception and therefore must be a pure class, whereas inheriting `caps.Control` would automatically add a capture set to that class. It's too late to revert for 3.8, but we should revert for 3.8.1. It's technically a backwards incompatible change, but I would be extremely surprised if anyone has used ReturnThrowable as a caps.Control in the 3.8.0 window. [Cherry-picked 5924e08]
