This variable is used in post-parse stage to declare that sum-functions,
or functions which have sense only if GROUP BY is present, are allowed.
For example in queries
SELECT MIN(i) FROM foo
SELECT GROUP_CONCAT(a, b, MIN(i)) FROM ... GROUP BY ...
MIN(i) have no sense.
Though it's grammar-related issue, it's hard to catch it out during the
parse stage because GROUP BY clause goes in the end of query. This
variable is mainly used in setup_fields/fix_fields.
See item_sum.cc for details.
