The "x IN (?)" optimization in check-ins [2ff3b25f40] and [e68b427afb] is
...
incorrect, as demonstrated by the in4-5.1 test case in this check-in.
The "COLLATE binary" that was being added to the RHS of IN was overriding
the implicit collating sequence of the LHS. This change defines the EP_Generic
expression node property that blocks all affinity or collating sequence
information in the expression subtree and adds that property to the expression
taken from RHS of the IN operator.

Previous check-in is not quite correct. "x IN (?)" is not exactly the same
