	epsilon destination.
	(duplicate_node_closure): New function.
	(duplicate_node): Remove the handling OP_CONTEXT_NODE.
	(calc_inveclosure): Likewise.
	(calc_eclosure): Likewise.
	(calc_eclosure_iter): Invoke duplicate_node_closure instead of
	direct invocation of duplicate_node.
	(parse): Don't use comma operator in the return to avoid compiler
	warning.
	(parse_reg_exp): Likewise.
	(parse_branch): Likewise.
	(parse_expression): Likewise.
	(parse_sub_exp): Likewise.
	(parse_dup_op): Likewise.
	* posix/regex_internal.c (re_dfa_add_node): Remove the substitutions
	which became useless.
	(create_ci_newstate): Remove the handling OP_CONTEXT_NODE.
	(create_cd_newstate): Likewise.
	* posix/regex_internal.h (re_token_type_t): Remove the obsolete type.
	(re_token_t): Likewise.
	(re_dfa_t): Likewise.
	(re_node_set_remove): New macro.
	* posix/regexec.c (check_matching): Remove the handling

	(pop_fail_stack): Fix the memory leak.
	(set_regs): Likewise.
	(free_fail_stack_return): New function.
	(sift_states_backward): Fix the memory leak.  Remove the handling
	OP_CONTEXT_NODE.
	(update_cur_sifted_state): Append some if clause to avoid redundant
	call.
	(sub_epsilon_src_nodes): Use IS_EPSILON_NODE since it might be a
	back reference.
	(check_dst_limits): Remove the handling OP_CONTEXT_NODE.
	(check_subexp_limits): Likewise.
	(search_subexp): Likewise.
	(sift_states_bkref): Likewise.
	(transit_state_mb): Likewise.
	(transit_state_bkref_loop): Likewise.
	(transit_state_bkref_loop): Likewise.
