	posix          : regexec.c 

Log message:
	(check_dst_limits): Hoist computation of the source
	and destination bkref_idx out of the loop.  Pass it to
	check_dst_limits_calc_pos.
	(check_dst_limits_calc_pos_1): New function, containing the recursive
	loop of check_dst_limits_calc_pos; uses the "more" field of
	struct re_backref_cache to control the loop.
	(check_dst_limits_calc_pos): Store into "boundaries" the position
	relative to lim's start and end positions.  Do not accept eclosures,
	accept bkref_idx instead.  Call check_dst_limits_calc_pos_1 to do the work.
	(sift_states_bkref): Use the "more" field of struct re_backref_cache
	to control the loop.  A big "if" was turned into a continue and the
	function was reindented.
	(get_subexp): Use the "more" field of struct re_backref_cache
	to control the loop.
	(match_ctx_add_entry): Initialize the bkref_ents' "more" field.
	(search_cur_bkref_entry): Return -1 if out of bounds.
