I implemented the second solution: recompute the profile information
after graphite code generation.

	* Makefile.in (graphite.o): Depends on PREDICT_H.
	* graphite.c: Include predict.h.
	(graphite_finalize): Call tree_estimate_probability.
	* predict.c (predict_loops): Do not call scev_initialize and
	scev_finalize.
	(tree_estimate_probability_bb): New.
	(tree_estimate_probability): Do not initialize loops: move that
	code to the driver.  Call tree_estimate_probability_bb.
	(tree_estimate_probability_driver): New.
	(pass_profile): Use tree_estimate_probability_driver.
	* predict.h (tree_estimate_probability): Declared.

I am regstrapping this patch on amd64-linux.  Okay for trunk if it passes?

Thanks,
Sebastian
