	* posix/regex_internal.c (re_node_set_init_1): Make it clean in case
	of malloc failure.
	(re_node_set_init_copy): Likewise.
	* posix/regex_internal.h (state_array_t): New structure.
	(re_sub_match_last_t): Likewise.
	(re_sub_match_top_t): Likewise.
	(re_match_context_t): Add new members.
	(re_dfa_t): Likewise.
	* posix/regexec.c (re_search_internal): Invoke prune_impossible_nodes
	to check the matching is really correct, and retry if failed.
	Move the routin pruning the impossible nodes from here, ...
	(prune_impossible_nodes): To this function.
	(check_matching): Invoke check_subexp_matching_top, and replace
	redundant checking with transit_state_bkref invocation.
	(proceed_next_node): Replace strncmp with memcmp.  Reported by
	Paolo Bonzini  <bonzini@gnu.org>.
	(update_cur_sifted_state): Remove search_subexp invocation.
	(search_subexp): Remove this function.
	(check_dst_limits_calc_pos): Use search_cur_bkref_entry for
	optimization.
	(sift_states_bkref): Use search_cur_bkref_entry for optimization.

	(check_subexp_matching_top): New function.
	(transit_state_bkref): Remove unused array.
	Merge transit_state_bkref_loop.
	(transit_state_bkref_loop): Use get_subexp instead of
	sift_states_backward.  Use search_cur_bkref_entry for optimization.
	Merge this function to transit_state_bkref.
	(get_subexp): New function.
	(get_subexp_sub): Likewise.
	(find_subexp_node): Likewise.
	(check_arrival): Likewise.
	(check_arrival_expand_ecl): Likewise.
