amd/common: fix build_cube_select
Fix the custom cube coord selection sequence to be identical to the hardware v_cubesc/tc and OpenGL spec. Affects texture sampling with user-provided derivatives. Fixes dEQP-GLES3.functional.shaders.texture_functions.texturegrad.* Cc: [email protected] Reviewed-by: Marek Olšák <[email protected]> Tested-by: Dieter Nützel <[email protected]>
