Model `defer`ed calls so the call runs at function exit rather than inline
at the `defer` statement, reproducing the previous control-flow semantics:

- Add a per-defer "defer-invoke" node for the deferred call.
- deferExitStep wires normal-exit predecessors (return nodes and body
  fall-through) through the active deferred-call invocations in
  last-in-first-out order, then on to the normal exit target (the
  result-read epilogue for named results, or the normal exit node).
- The chain is reachability-gated using the defer-free successor relation
  (succIgnoringDeferExit / isInOrderNode), so only deferred calls that were
  actually registered on a path are run on that path.
- overridesCallableBodyExit / overridesCallableEndAbruptCompletion suppress
  the default body-exit and return routing for functions containing
  `defer`, so the epilogue is interposed instead.
