This patch replaces the control flow handling with a new
pass which structurize the graph before transforming it to
machine instruction. This has a couple of different advantages
and currently fixes 20 piglit tests without a single regression.
It is now a general purpose transformation that could be not
only be used for SI/R6xx, but also for other hardware
implementations that use a form of structurized control flow.
v2: further cleanup, fixes and documentation

The Align parameter is a power of two, so 16 results in 64K
alignment. Additional to that even 16 byte alignment doesn't
make any sense, so just remove it.
