Yeah so this isn't going to fly. r600/radeonsi both expose PIPE_CAP_COMPUTE, for clover, but won't support these compute shaders quite yet. Not sure what the solution is here... maybe just add another cap? PIPE_CAP_GLSL_COMPUTE or something? Or require a backend to also set PIPE_CAP_GLSL_VERSION to 430 for ARB_compute_shader to become exposed? Don't know.
GLSL 430 also requires arrays_of_arrays. I don't actually know how much we need to do to support that, but maybe it'd be better not to depend on that.
A new cap is an option. A slightly weird but I think reasonable option would be to require a PIPE_CAP_GLSL_VERSION of 420, since ARB_compute_shader officially requires OpenGL 4.2 anyway, and then let us deal with the fallout when we up that version number.
