Add support for fragment shader interlock (#2768)

Browse source 
* Support coherent images

* Add support for fragment shader interlock

* Change to tree based match approach

* Refactor + check for branch targets and external registers

* Make detection more robust

* Use Intel fragment shader ordering if interlock is not available, use nothing if both are not available

* Remove unused field
