The idea is to switch from allocating separate buffers for shader data's structure of arrays to allocating one huge memory block and do some index trickery to make it accessed as SOA. This saves quite reasonable amount of lines of code in device_opencl and also makes it possible to get rid of special declaration of ShaderData structure. As a side effect it also makes it easier to experiment with SOA vs. AOS for split kernel. Works fine here on NVidia GTX580, Intel CPU amd AMD Fiji cards.
