Bug#18411494 WRONG COMPARSION ON BIG DECIMAL VALUES
Problem: integer literals may be converted to floats for
comparison with decimal data. If the integers are large,
we may lose precision, and give wrong results.
Fix: for
<non-const decimal expression> <cmp> <const string expression>
or
<const string expression> <cmp> <non-const decimal expression>
we override the compare_type chosen by item_cmp_type(), and
do comparison as decimal rather than float.
