  -----------
  [ORC] Remove EDU from dependants list of dependencies before destroying.

Dependant lists hold raw pointers back to EDUs that depend on them. We need to
remove these entries before destroying the EDU or we'll be left with a dangling
reference that can result in use-after-free bugs.

No testcase: This has only been observed in multi-threaded setups that
reproduce the issue inconsistently.
