[Mesa-dev] [PATCH 10/10] i965: Advertise our vertex shader texture units.

[Kenneth Graunke]

Previously, we advertised 0 VS texture units.  Now that we have proper
support for using the sampling engine in the VS, we can advertise 16,
which is conveniently the number required for OpenGL 3.0.

v2: Enable on Gen4.  I hacked up my tests to not use flat ivec varyings
    and they pass.
