af399884e1 Fix T44113: Ashikhmin-Shirley distribution of glossy shader at 0 roughness causes artifacts when background uses MIS 
Was a division by zero error, solved in the same way as beckmann/ggx
deals with small roughness values.

b12151eceb Cycles: glossy and anisotropic BSDF changes 
* Anisotropic BSDF now supports GGX and Beckmann distributions, Ward has been
  removed because other distributions are superior.
* GGX is now the default distribution for all glossy and anisotropic nodes,
  since it looks good, has low noise and is fast to evaluate.
* Ashikhmin-Shirley is now available in the Glossy BSDF.
