We needed the sese_mode_p functionality in the dominators pass to limit 
optimization scope to kernels regions. Now we no longer encounter 
kernels region in the kernels pass group, but split-off function that 
used to be  kernels region. So we no longer need this functionality.

This patch reverts the sese_mode_p functionality.
