Description:
------------
Specifying object as the type hint seems to be broken when using namespaces.

Test script:
---------------
namespace A;

class X {}

function foo(object $bar) {}

foo(new X);
foo(new \stdClass);

Expected result:
----------------
foo(new X); // works
foo(new \stdClass); // works

Actual result:
--------------
foo(new X); // fails
foo(new \stdClass); // fails
