EmptyString currently allows multiple instances, which is wasteful of space. We only need one instance of emptystring.

Modify compilerkit_empty_set_new so that it statically allocates a single instance of that object, which it returns.
Modify compilerkit_empty_set_dispose so that it doesn't bother to deallocate the instance.

This one will be a cakewalk now. :-)
