Please, ignore this patch. My findings in:
https://bugs.freedesktop.org/show_bug.cgi?id=87407

Are showing a possible bug in the limit values when using dFdx/dFdy in
combination with the abs() modifier.

Ian is recommending in that patch to actually replace this current
piglit test with individual shader_runner tests. I will work in this
direction in the bug above but, in the meanwhile, I'm posting next a
patch for testing the regular values and fix the compilation warnings.
