Split rewrite_cross_bb_scalar_deps_out_of_ssa out from rewrite_reductions_out_of_ssa.

2010-06-23  Sebastian Pop  <sebastian.pop@amd.com>

	* graphite-sese-to-poly.c (rewrite_cross_bb_scalar_deps_out_of_ssa):
	Split out of rewrite_reductions_out_of_ssa.
	* graphite-sese-to-poly.h (rewrite_cross_bb_scalar_deps_out_of_ssa):
	Declared.
	* graphite.c (graphite_transform_loops): Call it.
