ISSUE:       7025
TITLE:       Results of negation must be the same for each datatype (smallint / int /bigint / int128) when argument is least possible value for this type
DESCRIPTION: Confirmed 'sqltype: 496 LONG' for -(-2147483648). Before fix was: '580 INT64'.
FBTEST:      bugs.gh_7025
NOTES:
    [14.12.2023] pzotov
        Added 'SQLSTATE' in substitutions: runtime error must not be filtered out by '?!(...)' pattern
        ("negative lookahead assertion", see https://docs.python.org/3/library/re.html#regular-expression-syntax).
        Added 'combine_output = True' in order to see SQLSTATE if any error occurs.
