New implementation of Graphite. 

2009-07-30  Sebastian Pop  <sebastian.pop@amd.com>

	* Makefile.in (OBJS-common): Added dependence on graphite-blocking.o,
	graphite-clast-to-gimple.o, graphite-dependences.o,
	graphite-interchange.o, graphite-poly.o, graphite-ppl.o,
	graphite-scop-detection.o, graphite-sese-to-poly.o, and sese.o.
	(graphite-blocking.o,
	graphite-clast-to-gimple.o, graphite-dependences.o,
	graphite-interchange.o, graphite-poly.o, graphite-ppl.o,
	graphite-scop-detection.o, graphite-sese-to-poly.o, and sese.o): New.
	* cfgloop.c (alloc_loop): Set loop->can_be_parallel to false.
	* cfgloop.h (struct loop): Add can_be_parallel field.
	* common.opt (fgraphite-identity): Moved up.
	(fgraphite-force-parallel): New flag.
	* graphite.c: Rewrite.
	* graphite.h: Rewrite.
	* passes.c (init_optimization_passes): Schedule a pass of DCE and LIM
	after Graphite.
	* toplev.c (graphite_out_file): New file descriptor.
	(graphite_in_file): New.
	(process_options): flag_graphite_force_parallel cannot be used without
	Graphite.
	* tree-ssa-loop.c: Include toplev.h.
	(gate_graphite_transforms): Enable flag_graphite for
	flag_graphite_force_parallel.
