Bug description:Presence of __invoke makes protected __construct visible as 
callable

Description:
------------
Presence of __invoke causes  is_callable($obj, '__construct') returns true,


instead of false when it's called out of class scope.



Also, is_callable('class', '__construct') yields true even if __construct
is set 

to protected (which is clearly not connected with __invoke issue, but I
suppose 

that is caused by the same underlying problem).



Although setting __construct private/protected seems a little bit pervert,
if it 

is not interdicted by language semantics, visibility testing should give
good 

results. 

Test script:
---------------
class Singleton {

                protected static $aInstances = array();

                final protected function __construct(){}                        
                

                public static function getInstance(){

                $sClassName = get_called_class();

                        if (!isset(static::$aInstances[$sClassName])) {

                                static::$aInstances[$sClassName] = new 
$sClassName();           

                        } // if

                return static::$aInstances[$sClassName];                

                } // getInstance

        } // class

        

        class SingletonWithInvoke extends Singleton {                   

                final protected function __invoke(){}   

        } // class

                        

        var_dump(is_callable(Singleton::getInstance(), '__construct'));

        var_dump(is_callable(SingletonWithInvoke::getInstance(), 
'__construct'));

        var_dump(is_callable('Singleton', '__construct'));      

        var_dump(is_callable('SingletonWithInvoke', '__construct'));

Expected result:
----------------
bool(false) bool(false) bool(false) bool(false)

Actual result:
--------------
bool(false) bool(true) bool(true) bool(true)
