Persisting constants only if flag is set.
Basic forced autoloading for maglev_persistables.

Currently works only for one autoload per module.
Calls to autoload are cached, so that persistent associations can be created during
the call to maglev_persistable.
Turned autoload cache into a list, so multiple autoloads can happen in module.
Autoloads are automatically reloaded when called maglev_persistable is called.
