	(graphite.o-warn): Removed -Wno-error.
	* tree-parloops.c (canonicalize_loop_ivs): Allow reduction_list 
	to be a NULL pointer.  Call update_stmt.  Return the newly created

	(new_graphite_bb): Test for useful statements before building a
	graphite statement for the basic block.
	(free_graphite_bb): Do not free GBB_DATA_REFS: this is a bug
	in free_data_ref that calls BITMAP_FREE (DR_VOPS (dr)) without 
	reason.

	nb_reductions_in_loop, graphite_loop_normal_form): New.
	(scop_record_loop): Call graphite_loop_normal_form.
	(build_scop_loop_nests): Iterate over all the blocks of the
	function instead of relying on the incomplete information from
	SCOP_BBS.  Return the success of the operation.

	Use replace_exp	and update_stmt.
	(expand_scalar_variables_expr): Same.  Use the map to get the
	new names for the renaming of induction variables and for the
	renaming of variables after a basic block has been copied.
	(expand_scalar_variables): Same.
	(graphite_rename_variables): Renamed rename_variables.
	(move_phi_nodes): Removed.
	(get_false_edge_from_guard_bb): New.
	(build_iv_mapping): Do not insert the induction variable of a
	loop in the renaming iv map if the basic block does not belong
	to that loop.
	(register_old_new_names, graphite_copy_stmts_from_block,
	copy_bb_and_scalar_dependences): New.
	(translate_clast): Heavily reimplemented: copy basic blocks,
	do not move them.  Finally, in call cleanup_tree_cfg in gloog.
	At each translation step call graphite_verify ensuring the 
	consistency of the SSA, loops and dominators information.
	(collect_virtual_phis, find_vdef_for_var_in_bb,
	find_vdef_for_var_1, find_vdef_for_var,

	rewrite_into_sese_closed_ssa): New.
	(gloog): Remove dead code.  Early return if code cannot be
	generated.  Call cleanup_tree_cfg once the scop has been code
	generated.
	(graphite_trans_scop_block, graphite_trans_loop_block): Do not 
	block loops with less than two loops.

	(graphite_transform_loops): Call recompute_all_dominators: force the
	recomputation of correct CDI_DOMINATORS and CDI_POST_DOMINATORS.
