R600: Use StructurizeCFGPass for non SI targets
StructurizeCFG pass allows to make complex cfg reducible ; it allows a lot of
shader from shadertoy (which exhibits complex control flow constructs) to works
correctly with respect to CFG handling (and allow us to detect potential bug in
other part of the backend).
We provide a cmd line argument to disable the pass for debug purpose.
