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

Hi everyone,
I would like to upgrade some libraries for Cycles.

* LLVM 3.4: We use different versions here atm on our platforms, so it 
would be good to unify that and use the same on Windows, Linux and Mac.
* OIIO 1.4.11
* OSL 1.5 (currently still in RC3 phase)

I compiled the new OIIO and OSL on Windows x64 with msvc 2013 (still 
against LLVM 3.2 though) tonight to test this. Compilation was easy for 
the most part, I will submit some fixes upstream though.

Sergey, Jens, can you please take a look at this for Linux and Mac OS? 
You might want to wait for the final OSL release though, which should 
happen in a few days.

NOTE: The OSL API changed, so when you compile Blender with the new 
libs, you need to apply this patch first: https://developer.blender.org/D662
Once all platforms are upgraded I will commit this to master.
