Gun missing on BDW

One of the guns in Xontic does not render correctly on BDW.  However, the same
gun does render correctly on BYT.  At Ken's suggestion, I tried
INTEL_SCALAR_VS=0, but that did not help.

With some additional modifications to the driver, I can add '+r_glsl_skeletal
1' to the Xonotic command line.  This causes Xonotic to use a different
animation system that uses UBOs.  In this scenario, the gun is rendered
correctly.

I have also tried back as far as Mesa 13.0.0, and the bug still existed there. 
I will try older versions.

I have not tried hardware other than BDW and BYT.
