Go CFG: run deferred calls at function exit in LIFO order
...
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.

Accept change in test output
...
To determine that test9 can't return normally, you have to use the fact
that test5 can't return normally. This would make CFG construction
recursive, which would be bad for performance. Therefore we accept the
limitation that we cannot detect that test9 can't return normally, and
we change the test output.
