Description:
------------
When using a combined operator like += or ++ on an undefined class member, it does not produce "undefined property" notice as expected. Tested with all errors enabled.

Reproduce code:
---------------
$a+=5;
$b=new stdClass;
$b->a+=5;


Expected result:
----------------
Notice: Undefined variable: a
Notice: Undefined property: stdClass::$a

Actual result:
--------------
Notice: Undefined variable: a
