	* cfgloop.h (struct iv_occurence, iv_occurence_base_class,
	iv_occurence_step_class): New.
	(iv_occurences): Declare.
	(finalize_iv_analysis, analyse_induction_variables): Types changes.
	(iv_emit_insn_before, iv_emit_insn_after, prefetch_loop_arrays):
	Declare.
	* df.c (df_reg_table_realloc, df_link_create, df_insn_refs_record,
	df_bb_luids_set, df_refs_queue, df_refs_process): Export.
	(df_insn_ud_chain_create): Split from df_bb_ud_chain_create.

	df_insn_ud_chain_create, df_bb_luids_set, df_refs_queue,
	df_refs_process): Declare.
	* loop-iv.c (current_loops): New static variable.
	(iv_occurences): New variable.
	(fill_rd_for_defs, enter_iv_occurence, record_iv_occurences_1,

	type unnecesarily.  Use FOR_BB_INSNS.
	(initialize_iv_analysis): Initialize current_loops and
	iv_occurences.
	(finalize_iv_analysis, analyse_induction_variables): Use current_loops
	instead of loops parameter.
	(iv_emit_insn_before, iv_emit_insn_after): New.
	* loop.c (prescan_loop, strength_reduce, check_dbra_loop): Remove
	prefetching references.
