Description:
------------
When an class implements an interface and then uses a method defined in a trait for the implementation, the prototype of the method is not enforced.

Test script:
---------------
<?php

interface I {
    public function oneArgument($a);
}

trait T {
    public function oneArgument() {}
}

class C implements I {
    use T;
}


Expected result:
----------------
PHP Fatal error:  Declaration of C::oneArgument() must be compatible with C::oneArgument($a) in test.php on line 11

Actual result:
--------------
Script compiles and runs without error.

Log: Fixed Bug #60153 (Interface method prototypes not enforced when implementd via traits.)
# Moved the freeing of overriden functions to a point after the check.
# The new check comes after the normal inheritance check to give the first check
# the opportunity to abort with a more detailed error.
# Also fixed a small type in an unrelated test.
