The push-down optimization was being too aggressive such that it sometimes generated incorrect results. Reinstate the restriction (4) (with qualifications) that was removed by check-ins [b5d3dd8cb0b1e4] and [dd568c27b1d765]. (check-in: f08c1731b0 user: drh tags: trunk)

    To utilise "general" case mapping, the upper() or lower() scalar 
    functions are invoked with one argument:

        upper('ABC') -> 'abc'
        lower('abc') -> 'ABC'


    To access ICU "language specific" case mapping, upper() or lower()
    should be invoked with two arguments. The second argument is the name
    of the locale to use. Passing an empty string ("") or SQL NULL value
    as the second argument is the same as invoking the 1 argument version
    of upper() or lower():
