CDI_POST_DOMINATORS are not used in Graphite.

2010-09-20  Sebastian Pop  <sebastian.pop@amd.com>

	* graphite-clast-to-gimple.c (graphite_verify): Remove call to
	verify_dominators for CDI_POST_DOMINATORS.
	* sese.h: Remove comment about CDI_POST_DOMINATORS.
	(recompute_all_dominators): Remove call to free_dominance_info
	for CDI_POST_DOMINATORS.  Remove call to calculate_dominance_info
	for CDI_POST_DOMINATORS.
