Add a new shader attachment/link ordering test

Graphics / Mesa 3D Graphics Library / Piglit - Brian Paul [vmware.com] - 27 January 2015 18:38 UTC

AFAICT, the GL and GLSL specs don't say anything about the significance of the order in which shaders are attached to a program object. For example, if there's two vertex shader A and B, it shouldn't matter if they're attached in order A,B or B,A.

This pair of shader tests exercises that. Both pass with Mesa but the "b-a" case fails with NVIDIA.
