regcprop.c: Use rtx_insn 

gcc/
	* regcprop.c (struct queued_debug_insn_change): Strengthen field
	"insn" from rtx to rtx_insn *.
	(replace_oldest_value_reg): Likewise for param "insn".
	(replace_oldest_value_addr): Likewise.
	(replace_oldest_value_mem): Likewise.
	(apply_debug_insn_changes): Likewise for local "last_insn".
	(copyprop_hardreg_forward_1): Likewise for local "insn".
