Lukas Stockner d9281a6332 Cycles: Fix three numerical issues in the fresnel, normal map and Beckmann code 
- In fresnel_dielectric, the differentials calculation sometimes divided by zero.
- When the normal map was (0.5, 0.5, 0.5), the code would try to normalize a zero vector. Now, it just uses the regular normal as a fallback.
- The approximate error function used in Beckmann sampling sometimes overflowed to inf while calculating r^16. The final value is 1 - 1/r^16, however,
  so now it just returns 1 if the computation would overflow otherwise.
