[relate] Add optimization to A/A skipping parts of the algorithm if it's not possible to change the final result.

Browse Source 
Add may_update() funcionality which may be used if it's possible to change the result for the specified matrix fields and overlap dimension.
Initialize flags in no_turns_aa_pred and uncertain_rings_analyser with values calculated using this functionality.
Add manual checks around the parts of areal_areal::apply() where IPs are sorted and analysed.
