	DF_INSN_INFO_EQ_USES): New.
	(DF_INSN_LUID, DF_INSN_DEFS, DF_INSN_USES, DF_INSN_EQ_USES,
	DF_INSN_UID_LUID, DF_INSN_UID_DEFS, DF_INSN_UID_USES,
	DF_INSN_UID_EQ_USES): Rewrite using DF_INSN_INFO_* macros.
	* df-core.c: Update comment for above changes.
	(df_insn_debug_regno): Use DF_INSN_INFO_GET instead of INSN_UID and
	DF_INSN_UID_* macros.
	(df_ref_debug): Check for NULL DF_REF_INSN_INFO.
	* df-scan.c (df_ref_record): Take a df_insn_info instead of an
	insn rtx.  Update all callers.

	df_ref_create_structure, df_insn_refs_collect): Likewise.
	(df_ref_equal_p): Compare DF_REF_INSN_INFO pointers for the refs.
	* df-problems.c (df_chain_dump): Test for non-NULL DF_REF_INSN_INFO.
	(df_live_bb_local_compute): Retrieve DF_INSN_INFO, use DF_INSN_INFO_*
	macros to access the insn refs.
	(df_chain_top_dump, df_chain_bottom_dump, df_byte_lr_alloc): Likewise.
	* fwprop.c (use_killed_between): Use DF_REF_INSN accessor macro.
	(all_uses_available): Retrieve DF_INSN_INFO for def_insn, and use it
	for accessing the refs.

	to look at the insn refs.
	(record_uses): Likewise.
	* dce.c (deletable_insn_p): Don't tolerate artificial DEFs in this
	function anymore.
	(mark_artificial_uses): Don't mark_insn for artificial refs.
