Subject: Bug #55615 and bug #55564

An user assignment variable expression that's
evaluated in a logical expression context
(Item::val_bool()) can be pre-calculated in a
temporary table for GROUP BY.
However when the expression value is used after the
temp table creation it was re-evaluated instead of
being read from the temp table due to a missing
val_bool_result() method.
Fixed by implementing the method.
