[PATCH 051/236] bb-reorder.c: Use rtx_insn


gcc/
	* bb-reorder.c (copy_bb_p): Strengthen local "insn" from rtx to
	rtx_insn *.
	(get_uncond_jump_length): Likewise for locals "label", "jump".
	(fix_up_crossing_landing_pad): Likewise for locals "new_label",
	"jump", "insn".
	(add_labels_and_missing_jumps): Likewise for local "new_jump".
	(fix_up_fall_thru_edges): Likewise for local "old_jump".
	(find_jump_block): Likewise for local "insn".
	(fix_crossing_conditional_branches): Likewise for locals
	"old_jump", "new_jump".
	(fix_crossing_unconditional_branches): Likewise for locals
	"last_insn", "indirect_jump_sequence", "jump_insn", "cur_insn".
	(pass_duplicate_computed_gotos::execute): Likewise for local "insn".
