	* graphite-blocking.c (pbb_strip_mine_loop_depth): Renamed
	pbb_strip_mine_time_depth.  Changed the implementation so that
	transformation is expressed as a transformation on
	time (scatttering) dimensions.  Also, ensures that the 2d+1
	scheduling format is preserved.
	(pbb_strip_mine_profitable_p): Profitability is based on the
	iteration number of a given time (scattering) dimension,
	and not on a original loop depth dimension.
	(pbb_strip_mine): Call pbb_number_of_iterations_at_time.
	(pbb_do_strip_mine): Call psct_dynamic_dim.
	* graphite-poly.c (pbb_number_of_iterations_at_time): New.
	* graphite-poly.h (pbb_number_of_iterations_at_time): Declared.
	(pbb_nb_dynamic_scattering_transform): New.
	(psct_dynamic_dim): New.
