* graphite-scop-detection.c
	(scop_detection::stmt_has_simple_data_refs_p): Always use
	the full nest as region.
	(try_generate_gimple_bb): Likewise.
	* sese.c (scalar_evolution_in_region): Simplify now that
	SCEV can handle instantiation in regions.
	* tree-scalar-evolution.c (instantiate_scev_name): Also instantiate
	in the non-loop part of a function if requested.
