	not call finish_vinsn.
	(emit_single_op): Use bundle_tinsn instead of bundle_single_op.
	(relax_frag_immed): Get num_slots from cur_vinsn.
	(convert_frag_narrow): Update call to xg_emit_insn_to_buf.
	(convert_frag_immed): Likewise.  Also, get num_slots from cur_vinsn.
	(init_op_placement_info_table): Set narrowest_slot field.  Remove
	code for deleted fields.
	(xg_get_single_size): Return narrowest_size field, not single_size.
	(xg_get_single_format): Return narrowest field, not single.
	(xg_get_single_slot): New.
