[Mesa-dev] [PATCH 03/14] glsl: Add a new ast_type_qualifier::has_auxiliary_storage() method.

[Kenneth Graunke]

"Auxiliary storage qualifiers" is the new term given to "centroid",
"patch", and "sample" by GLSL 4.20/GL_ARB_shading_language_420pack.

Even though we only support "centroid", it's useful to add this now
so that all auxiliary storage qualifiers get handled in the right places
once they're eventually supported.
