Description:
------------
The Reflection classes do not trigger __autoload() when 
the class is undefined. This works correctly for 
userland classes.

Reproduce code:
---------------
function __autoload($c) {
	class autoload_class {
		public function __construct() {
			print "autoload success\n";
		}
	}
}

Reflection:export(new Reflection_Class('autoload_class'));

Expected result:
----------------
autoload success
Class [ <user>  class autoload_class ] {
  @@ /Users/adam/Desktop/autoload.php 4-10
