Calendar_get_debug_info() created a temporary IntlTimeZone wrapper zval via
timezone_object_construct() and never released it, leaking one wrapper object
per var_dump()/debug dump of an IntlCalendar instance. The wrapper is now
released with zval_ptr_dtor() after its debug info has been copied into the
result. Other timezone_object_construct() call sites write into return_value
and are refcount-managed. No other intl get_debug_info handler constructs a
temporary wrapper.
