[Piglit] [PATCH 0/6] ARB_shader_ballot tests

[Nicolai Hähnle]

Hi,

this series adds some basic tests for the builtin functions and
variables of the ARB_shader_ballot extension.

I have only tested this against my own work-in-progress implementation.
If somebody got to test it against the AMD or Nvidia blobs, that would
be much appreciated.

Please review!

Thanks,
Nicolai
