This patch generalizes the OSL support in Cycles to include GPU device types and adds an implementation for that in the OptiX device. There are some caveats still, including simplified texturing due to lack of OIIO on the GPU and a few missing OSL intrinsics. Note that this is incomplete and missing an update to the OSL library before being enabled! The implementation is already committed now to simplify further development.
