Make print_scop output the scoplib format.

2010-03-16  Sebastian Pop  <sebastian.pop@amd.com>

	* graphite-poly.c (print_scattering_function): Pretty print following
	the scoplib format.
	(print_pdr): Same.
	(print_pbb_domain): Same.
	(dump_gbb_cases): Same.
	(dump_gbb_conditions): Same.
	(print_pdrs): Same.
	(print_pbb): Same.
	(print_scop_params): Same.
	(print_scop_context): Same.
	(print_scop): Same.
	(print_pbb_body): New.
	(lst_indent_to): New.
	(print_lst): Start new lines with a #.
	* graphite-poly.h (pbb_bb): New.
	(pbb_index): Use pbb_bb.
	* graphite-ppl.c (ppl_print_powerset_matrix): Print the number of
	disjuncts.
	* tree-data-ref.c (dump_data_reference): Start new lines with a #.
