fbb24d1092 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.
