    Expand atomic GDS operations exposure support..



       have seen AMD IL/HW guides and seems evergreen an up support expanded GDS operations for example atomic logic ops (or,and,etc..) and arithmetic (atomic add etc..) so I request improve upon atomic counter support from least effort to more:

      (Note response in twitter from Graham Sellers (OGL AMD driver guy) from AMD seems working to expose that):

      *at least expose more than 8 atomic counts: >=256 ideal case as these allows me to calculate very fast histograms using an array of 256 atomic counters atomiccounter[inputdata]

      *expose as said existing GDS HW support for arithmetic and logic ops

      *the general way expose a GDS adress space similar to __global or __local could be __fastglobal

      Hope supports for this comes this year
