Description:
------------
In runkit 0.9

When runkit.internal_override is enabled (=1) re-declaring normal non-user-defined functions works fine however you cannot re-declare or add a method to a non-user-defined class, it returns the error: "class [] is not a user-defined class".

Perhaps this is due to RUNKIT_G(internal_override) not being checked in runkit_methods.c?


Reproduce code:
---------------
echo runkit_method_redefine(
   'DOMElement',
   'insertBefore',
   '$test',
   'return $test;',
   RUNKIT_ACC_PUBLIC
);

echo runkit_method_add(
   'DOMElement',
   'myAddedMethod',
   '$test',
   'return $test;',
   RUNKIT_ACC_PUBLIC
);

Expected result:
----------------
11

Actual result:
--------------
Warning: runkit_method_redefine() [function.runkit-method-redefine]: class domelement is not a user-defined class..

Warning: runkit_method_add() [function.runkit-method-add]: class domelement is not a user-defined class...
