glsl: Relax qualifier ordering restriction in ES 3.1.
... and allow the "binding" qualifier in ES 3.1 as well. GLSL ES 3.1 incorporates only a few features from the extension ARB_shading_language_420pack: the relaxed qualifier ordering requirements and the binding qualifier. Cc: "11.1" <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
