    arb_gpu_shader5: Add a test for instanced GS inputs.

    None of our other tests for instanced geometry shaders transfered
    the vertices to the geometry shader from the vertex shader via
    gl_Position.

    This used to be broken with the i965 driver's in Mesa 12.1.0
    on revision d10ae20b9678f1a5b8a81716c68e612662665277.
