r600g: Add support for relative addressing on constant buffers.
Relative addressing of constant buffers can't work properly through the kcache, since you can only address within the currently locked kcache window. Instead, this patch binds the constant buffer as a shader resource, and then explicitly fetches the constant using a vertex fetch with fetch type VTX_FETCH_NO_INDEX_OFFSET from the shader. There's probably still some room for improvement, doing the fetch right before the instruction that needs the value may not be quite optimal for example.
