Fix T42621: Glossy world ray visibility affects on transmission rays
There seems to be inconsistency in flags checks in Cycles kernel. In the
interface
glossy means "Glossy Reflection" and it is properly taken into account when
doing
visibility check in BVH traversal.
The check in indirect background/light emission was treating this flags as "any
of
glossy reflection or transmission" which is kind of weird.
Made it so emission code follows ray visibility assumptions in other parts of
the
kernel now.
