Mikhail 21bc1a99ba Cycles: optimize ensure_valid_reflection(), reduces render time by about 1%
This is an implementation that is about 1.5-2.1 times faster. It gives a result
that is on average 6° different from the old implementation. The difference is
because normals (Ng, N, N') are not selected to be coplanar, but instead
reflection R is lifted the least amount and the N' is computed as a bisector.
