spu.c: Include "cfgloop.h".

Browse Source 
* config/spu/spu.c: Include "cfgloop.h".
	(spu_machine_dependent_reorg): Call loop_optimizer_init and
	loop_optimizer_finalize.  Use bb_loop_depth instead of loop_depth.
	Directly compare loop_father values where appropriate.
	* config/spu/t-spu-elf (spu.o): Update dependencies.
