Nathan Vegdahl d9192aaa6d Cycles: limit the internal sample index of Sobol-Burley for performance 
This is done based on the render sample count so that it doesn't impact
sampling quality. It's similar in spirit to the adaptive table size in D16561,
but in this case for performance rather than memory usage.
