Subject: [PATCH] Fixed bug #68103 Dupplicate entry in Reflection

$ php -r '$r=new ReflectionExtension("pthreads"); print_r($r->getClassNames());'
Array
(
    [0] => Threaded
    [1] => stackable
    [2] => Thread
    [3] => Worker
    [4] => Mutex
    [5] => Cond
    [6] => Collectable
    [7] => Pool
)

In getClasses() output, it is possible to compare key (ex "stackable")
with $obj->name (ex "Threaded") to detect class alias.

...
    [Threaded] => ReflectionClass Object
        (
            [name] => Threaded
        )
    [stackable] => ReflectionClass Object
        (
            [name] => Threaded
        )
...
