8044e5f2d7 Cycles: Make BVH wider prior to packing 
This allows to do more non-trivial tree modifications to make
it more dense and more friendly for vectorization.

cb4b5e12ab Cycles: Cleanup, spacing after preprocessor 
It is supposed to be two spaces before comment stating which if
else/endif statements corresponds to. Was mainly violated in the
header guards.

73f2056052 Cycles: Add BVH8 and packeted triangle intersection 
This is an initial implementation of BVH8 optimization structure
and packated triangle intersection. The aim is to get faster ray
to scene intersection checks.

victor                 23:39.65   22:53.71

As memory goes, peak usage raises by about 4.7% in a complex
scenes.

Note that BVH8 is disabled when using OSL, this is because OSL
kernel does not get per-microarchitecture optimizations and
hence always considers BVH3 is used.

Original BVH8 patch from Anton Gavrikov.
Batched triangles intersection from Victoria Zhislina.
Extra work and tests and fixes from Maxym Dmytrychenko.
