It is undefined behavior when an ARB assembly or shadow2d GLSL func
uses SHADOW2D target with a texture in not depth format.
In this case AMD and NVIDIA automatically replaces SHADOW sampler
with a normal sampler and some games like Penumbra Overture which abuses
this UB works fine but breaks with mesa.
Replace the shadow sampler with a normal one here by recompiling
the ARB program variant
