Internal enums can be cloned and compared

[arnaud-lb]

Description

The following code:

<?php

var_dump(clone(ZendTestIntEnum::Foo) === ZendTestIntEnum::Foo);

Resulted in this output:

bool(false)

But I expected this output instead:

Uncaught Error: Trying to clone an uncloneable object of class ZendTestIntEnum

This is because we don't override the default object handlers in zend_register_internal_enum().
