Simplification: Remove the ply-5 continuation history update Simplification: The ply-5 continuation history update was added in #5792 together with a matching read in move ordering. #5978 removed that read as a simplification but kept the update, which has the smallest weight of any ply (66). This patch removes the ply-5 update too and drops the last CMHC multiplier which is no longer reachable.
