Nouveau - Jul 2015 - [Mesa-dev] [PATCH] nvc0: fix geometry program revalidation of clipping params

Even though in practice a geometry program will never be using UCP's,
we still were revalidating (aka recompiling) the program when more
clip planes became enabled (which also are used for regular clip
distances).

This seems like it should have led to massive fail, but I guess you
don't change the number of clip planes when using geometry shaders.
But I'm going to put this through a full piglit run just in case
there's something I'm missing.

What piglit test does this fix?

Any one which, after using a geometry shader, enables an extra clip
distance. i.e. none.
