42305fc126 Disable the reuse of IN-clause subqueries if the subquery is an explicit 
"SELECT ALL".  The ALL keyword is almost never used in actual practice (most
developers don't even know it can be used) so this should not interfere with
the optimization, but it does give us a convenient way to turn it off for
testing purposes.
