r600: Enable sb for nir only on specific request

Browse Source 
SB si known to be buggy and the ultimate aim is to make it go away. To
test workloads with better optimizations it makes sense to be able to
enable SB, but for the NIR backend it should not be enabled together
with NIR the default. Therefore an a specific debug option "nirsb" that
enables NIR with SB.
