Bug #30832: Assertion + crash with select name_const('test', now());
The NAME_CONST function is required to work correctly with constants only.
When executed with functions that return types other than those returned by
Item::field_type (string, int, decimal, or real), the result gets cast to
one of those types. This cannot happen for constants.
Fixed by only allowing constants as arguments to NAME_CONST.
