[Bf-cycles] Cycles lib upgrade (LLVM / OIIO / OSL)

[Sergey Sharybin]

We can't switch to LLVM-3.4 so easily, it defines some functions in the
global context which conflicts with the Collada library:
http://www.pasteall.org/53009

Either Collada or LLVM (or both) are to switch to less generic naming for
those functions, otherwise we'll make it impossible to compile blender by
the guys who're using system libs (including platform maintainers in
various linux distros).
