[Piglit] Patch to test for ARB_clip_control v2

[Ilia Mirkin]

Can you verify that your test fails with an incorrect implementation?
I just set nvc0 so that it always acts as if clip_halfz == 0, and the
test passed...

Also, you sent the patches inline just fine for mesa... can you do it
here as well? It enables people to review your patches...
