bpo-38070: visit_decref() calls _PyObject_IsFreed() (GH-15782)

In debug mode, visit_decref() now calls _PyObject_IsFreed() to ensure
that the object is not freed. If it's freed, the program fails with
an assertion error and Python dumps informations about the freed
object.
(cherry picked from commit d91d4de31745fc1ed4c7e6c208917827c9c472b6)
