Description:
------------
PHP 7 allows interfaces with final and abstract methods.

Test script:
---------------
<?php
interface test
{
    final function test1();
    abstract function test2();
}


Expected result:
----------------
Fatal error: Access type for interface method test::test1() must be omitted in /in/vqFDT on line 5

When the first mistake is fixed, then

Fatal error: Access type for interface method test::test2() must be omitted in /in/vqFDT on line 6

Actual result:
--------------
no errors
