make check-unit: use after free in test-opts-visitor
In the struct OptsVisitor, the 'repeated_opts' member points to a list
in the 'unprocessed_opts' hash table after the list has been destroyed.
A subsequent call to visit_type_int() references the deleted list.
It results in use-after-free issue reproduced by running the test case
under the Valgrind: valgrind tests/test-opts-visitor.
A new mode ListMode::LM_TRAVERSED is declared to mark the list
traversal completed.
