Branch: master
Commit: 4c8750015b23207de0b44f39bd33bb556268b51d
URL: http://cgit.freedesktop.org/mesa/mesa/commit/?id=4c8750015b23207de0b44f39bd33bb556268b51d

glsl: add ARB_texture_cube_map_array support (v2)
This adds all the new builtins + the new sampler types,
and hooks them up if the extension is supported.
v2: fix missing signatures for grad/lod
fix missing textureSize clarifications
fix compare vs starts with usage
