Fix Graphite memory leaks.

2010-09-23  Sebastian Pop  <sebastian.pop@amd.com>

	* graphite-clast-to-gimple.c (compute_bounds_for_level): Free le
	and ps.
	* graphite-poly.c (pbb_number_of_iterations_at_time): Free le and
	domain.
	* graphite-sese-to-poly.c (add_upper_bounds_from_estimated_nit):
	Do not allocate ub_expr, it is passed in initialized.
