* 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.
