Description:
------------
Operator Precedence doesn't seem to work as in earlier versions/expected.
Following http://de.php.net/manual/en/language.operators.php#language.operators.precedence
&& should have a higher priority than "or" and || should have a higher priority than "and".
It doesn't work anymore..

Reproduce code:
---------------
<?php
$foo1=1;
$foo2=1;
$foo3=0;
if($foo1==0 && $foo2==0 or $foo3==0){
	echo '<br>This should not happen';
}else{
	echo '<br>This should happen';
}
$bar1=0;
$bar2=1;
$bar3=1;
if($bar1==0 || $bar2==0 and $bar3==0){
	echo '<br>This should happen';
}else{
	echo '<br>This should not happen';
}
?>

Expected result:
----------------
This should happen
This should happen

Actual result:
--------------
This should not happen
This should not happen
