Bug description:\DirectoryIterator, parent::__construct() and \LogicException

Description:
------------
In PHP 5.4, an exception was throwed if a call to parent::__construct() is
not done in the constructor of a class which extends \DirectoryIterator.
Exception was not throwed in previous version of PHP, so it's a BC break.
And this BC break must be annoying in unit test, because it's impossible to
mock the \DirectoryIterator class.

Test script:
---------------
<?php

class myDirectoryIterator extends \DirectoryIterator
{
	public function __construct()
	{
	}
}

$directoryIterator = new myDirectoryIterator();

?>

Expected result:
----------------
Nothing.

Actual result:
--------------
Fatal error: Uncaught exception 'LogicException' with message 'In the
constructor of myDirectoryIterator, parent::__construct() must be called
and its exceptions cannot be cleared' in /path/to/directoryIterator.php:10
Stack trace:
#0 /path/to/directoryIterator.php(10):
myDirectoryIterator->internal_construction_wrapper()
#1 {main}
  thrown in /path/to/directoryIterator.php on line 10
