	* posix/regex_internal.h (re_match_context_t): Add a new member.
	(re_fail_stack_ent_t): New structure.
	(re_fail_stack_t): Likewise.
	* posix/regexec.c (re_search_internal): Use the new member of
	re_match_context_t.
	Use fail stack only if it has back references and there are plural
	matching candidates.
	(proceed_next_node): Use fail stack if it is indicated.
	(set_regs): Likewise.
	(push_fail_stack): New function.
	(pop_fail_stack): New function.
	(check_dst_limits): Likewise.
	(check_dst_limits_calc_pos): Likewise.
	(search_subexp): Check the limitations on the top of subexpressions.
	(sift_states_bkref): Check the limitations of the destination node.
	Reuse the array sctx->sifted_states.

	* stdio-common/printf_fp.c: Shuffle a few lines around to help the
	compiler optimizing.  No semantical changes intended.
