[Bf-cycles] Watertight Intersection?

[Sergey Sharybin]

Watertight ray-to-triangle intersection addresses problem when intersection
might be wrongly ignored in the cases when ray hits edge of triangle,
causing light leaks.

Example of issues caused by non-watertight intersection nature could be
found in the tracker, for example https://developer.blender.org/T34094
