This actually had nothing specific to new split normals, it was an internal limitation of BI raytracer, which would check against neighbor face shadowing only when they shared a common vertex, now it also performs checks when both faces have a vertex with a common "ancestor" (org index). Note this allows to also fix same issue when using SplitEdges modifier (and potentially others?), but only when AutoSmooth is enabled (due to some compute/mem overhead, we do not want to enable this code systematically). Thanks to Brecht for advices and review!
