* graphite-poly.c (new_poly_bb): Returns a poly_bb_p. Do not take
the reduction bool in parameter. Clear PBB_IS_REDUCTION. Set GBB_PBB.
* graphite-poly.h (new_poly_bb): Update declaration.
(gbb_from_bb): Moved here...
(pbb_from_bb): New.
* graphite-sese-to-poly.c (var_used_in_not_loop_header_phi_node):
Removed.
(graphite_stmt_p): Removed.
(try_generate_gimple_bb): Returns a gimple_bb_p. Do not pass in
sbitmap reductions. Always build a gimple_bb_p. Do not call
new_poly_bb.

(build_scop_drs): Call analyze_drs. Remove all the PBBs that do
not contain data references.
(new_pbb_from_pbb): New.
(insert_out_of_ssa_copy_on_edge): Call new_pbb_from_pbb after a
block is split.
(rewrite_close_phi_out_of_ssa): Update call to
insert_out_of_ssa_copy_on_edge.

(rewrite_commutative_reductions_out_of_ssa): Same.
(build_poly_scop): Call build_scop_bbs,
rewrite_commutative_reductions_out_of_ssa,
rewrite_reductions_out_of_ssa, and
rewrite_cross_bb_scalar_deps_out_of_ssa. Move build_scop_drs
before scop_to_lst.
* graphite-sese-to-poly.h (rewrite_commutative_reductions_out_of_ssa):
Removed declaration.
