Subject: Implement Shader Instructions SUATOM and SURED (#2090)

* Initial Implementation

* Further improvements (no support for float/64-bit types)

* Merge atomic and reduce instructions, add missing format switch

* Fix rebase issues.

* Not used.

* Whoops. Fixed.

* Partial implementation of inc/dec, cleanup and TODOs

* Remove testing path

* Address Feedback
