Test a pure depth write with conditional discard in the fragment shader.
This currently fails in radeonsi.

Good point.
Oh, and this should probably go into tests/spec/glsl-1.10
(hm, seems like piglit only has tests for discard starting glsl
1.30... but I assume it was a feature in 1.10 too? odd.)
There are more discard tests in tests/shaders, which is why I put that
here. But sure, I can put this in tests/spec/glsl-1.10. Probably makes
sense to move the others as well while I'm at it, what do you think?
Cheers,
Nicolai
