Mike Ash 2452f27e0f [6.2][RemoteMirror] Only look through Task wait adapters when there's a dependency record. ...

When the RunJob pointer is set to adapters, we try to get the "real" run pointer from the context. However, there are cases where the context can be a dangling pointer, when the task has finished with it but hasn't reset the pointer to anything else. For cases where that can happen, the context is legitimate only when there's a dependency record. Check for a dependency record before trying to read the context in those cases.

In most uses this will fail gracefully or return a garbage run pointer, but swift-reflection-test uses an in-process memory reader which can crash when trying to chase this pointer, resulting in test failures.
