* config/bfin/bfin.h (splitting_loops): Declare.

	* config/bfin/bfin.h (splitting_loops): Declare.
	* config/bfin/bfin-protos.h (WA_05000257, WA_05000283, WA_05000315):
	Reorder bit definitions to be ascending.
	(WA_LOAD_LCREGS, ENABLE_WA_LOAD_LCREGS): New macros.
	* config/bfin/bfin.c (splitting_loops): New variable.
	(bfin_cpus): Add WA_LOAD_LCREGS as needed.
	(struct loop_info): Remove members INIT and LOOP_INIT.
	(bfin_optimize_loop): Don't set them.  Reorder the code that generates
	the LSETUP sequence.  Allow LC to be loaded from any register, but also
	add a case to push/pop a PREG scratch if ENABLE_WA_LOAD_LCREGS.
	(bfin_reorg_loops): When done, split all BB_ENDs with splitting_loops
	set to 1.
	* config/bfin/bfin.md (loop_end splitter): Use splitting_loops instead
	of reload_completed.
	From Jie Zhang:
	* config/bfin/bfin.md (movsi_insn): Refine constraints.
