Review request for KDevelop.


Description
-------

Add support for PHP 5.5's array literal dereferencing.

This would for example look like this:

$a = [1,2,3][0];

where $a = 1;

The rfc detailing the feature can be found here: https://wiki.php.net/rfc/constdereference

I had to rewrite the array handling a little bit to make the typing work as expected and adjusted the unit tests for that as well.
