config/bfin: Use rtx_insn 

gcc/
	* config/bfin/bfin-protos.h (asm_conditional_branch): Strengthen
	param 1 from rtx to rtx_insn *.

	the various locals named "insn".
	(expand_epilogue_reg_restore): Likewise.

	(branch_dest): Likewise for param "branch".
	(asm_conditional_branch): Likewise for param "insn".
	(gen_one_bundle): Likewise for elements of param "slot" and local
	"t".
	(bfin_gen_bundles): Likewise for locals "insn", "next" and
	elements of local "slot".
	(reorder_var_tracking_notes): Likewise for locals "insn", "next",
	"queue", "next_queue", "prev".
