ree.c: Use rtx_insn 

gcc/
	* ree.c (struct ext_cand): Strengthen field "insn" from rtx to
	rtx_insn *.
	(combine_set_extension): Likewise for param "curr_insn".
	(transform_ifelse): Likewise for param "def_insn".
	(get_defs): Likewise for param "def_insn".  Strengthen param "dest"
	from vec<rtx> * to vec<rtx_insn *> *.
	(is_cond_copy_insn): Likewise for param "insn".
	(struct ext_state): Strengthen the four vec fields from vec<rtx>
	to vec<rtx_insn *>.
	(make_defs_and_copies_lists): Strengthen param "extend_insn" and
	local "def_insn" from rtx to rtx_insn *.
	(get_sub_rtx): Likewise for param "def_insn".
	(merge_def_and_ext): Likewise.
	(combine_reaching_defs): Likewise.
	(add_removable_extension): Likewise for param "insn".
	(find_removable_extensions): Likewise for local "insn".
	(find_and_remove_re): Likewise for locals "curr_insn" and
	"def_insn".  Strengthen locals "reinsn_del_list" and
	"reinsn_del_list" from auto_vec<rtx> to auto_vec<rtx_insn *>.
