	* graphite-poly.c (apply_poly_transforms): Implement the high
	level driver for flag_loop_block.
	* tree-ssa-loop.c (gate_graphite_transforms): Remove call to sorry for
	flag_loop_block.

	* gcc.dg/graphite/graphite.exp (DEFAULT_CFLAGS_GRAPHITE_BLOCK): Add
	-floop-block.
	* gfortran.dg/graphite/graphite.exp (DEFAULT_CFLAGS_GRAPHITE_BLOCK):
	Add -floop-block.
