This change set implements support for disassembly 8-bit arithmetic in Midgard, as exposed via the (u)char OpenCL types. This is far from complete, but it does a decent job for some more basic 8-bit-using shaders.
This is a prerequisite to a decent implementation of programmatic blending, since the blend pipeline is required to pack the pixel format itself. For RGBA8, this means some 8-bit arithmetic in the blend shader.
