patch 8.0.0554: toupper and tolower don't work properly for Turkish

    patch 8.0.0554: toupper and tolower don't work properly for Turkish

    Problem:    Toupper and tolower don't work properly for Turkish when 'casemap'
                contains "keepascii". (Bjorn Linse)
    Solution:   When 'casemap' contains "keepascii" use ASCII toupper/tolower.
