I don't think this is sufficient to get the CL 1.2+ image formats fully
working, at least you're going to need to add support for array and
buffer images to the memory transfer commands from api/transfer.cpp,
implement several missing image-related queries from CL 1.2, fix the
gallium pipe_resource and transfer glue code to work with the new memory
object types, and fix the LLVM interfacing code and compute kernel
handling to accept the new image types as kernel argument.  Still a
bunch of work to do, but this seems like a good start... :)
