* graphite-isl-ast-to-gimple.c (translate_pending_phi_nodes):
Verify both BBs contain loop PHI nodes before dispatching to
copy_loop_phi_args.
(graphite_regenerate_ast_isl): Do not recompute dominators,
do not verify three times. Restructure for clarity.
* graphite-scop-detection.c (same_close_phi_node,
remove_duplicate_close_phi, make_close_phi_nodes_unique,
defined_in_loop_p, canonicalize_loop_closed_ssa,
canonicalize_loop_closed_ssa_form): Simplify, remove excess
checking and SSA rewrite, move to ...
* graphite.c: ... here. Include ssa.h and tree-ssa-loop-manip.h.
(graphite_initialize): Do not pass in ctx, do not reset the
SCEV cache, compute only dominators.
(graphite_transform_loops): Allocate ISL ctx after
graphite_initialize. Call canonicalize_loop_closed_ssa_form.
Maintain post-dominators only around build_scops.
* sese.c (if_region_set_false_region): Make static. Free
and recompute dominators.
(move_sese_in_condition): Assert we don't get called with
post-dominators computed.
* sese.h (if_region_set_false_region): Remove.
