Fix T43511: Major slow down with many instanced objects in cycles GPU

Browse Source 
Slowdown was caused by watertight intersection commit and follow-up workaorund
for compiler crash which uninlined utility function which rotates the ray.

Now it's only uninlined for sm_50 and sm_52 experimental kernels which are the
only ones which failed to compile.

Rendering still might be a bit slower but at least shouldn't be that dramatic.
