drh fbfd113365 Reinstate the optimization of converting "a IN (C)" into "a=C" but only 
if C is a constant.  If the RHS is a table column, the complications of
managing affinity and collations become too involved to mess with.

drh 4fc836546e Fix a bug introduced earlier today by check-in [88833a9c2849c959]. 
Ticket [29f635e0af71234b]

FossilOrigin-Name: 6e7b4527d32cc1be0294614b9d7363d4b59cf654a954b86515b3f6888975ce73

drh dd668c26b5 When applying the IN_INDEX_NOOP optimization and the LHS has REAL affinity, 
also apply REAL affinity to each element of the RHS.

drh 7ec796d002 Add ALWAYS() to an always true conditional that results from the 
previous check-in.  Add a test case for ticket [dbaf8a6820be1ece] to
supplement those already checked into TH3.

drh 42be2ad30b Make sure the affinity of the RHS of an IN operator does not affect the 
outcome even if the RHS expression contains a COLLATE clause.

drh 042666e4fa When an IN operator drives a query loop, mark it as "CODED" so that it 
will not be used afterwards for a (pointless) membership test.  This is
a better fix for ticket [df46dfb631f75694] than the previous fix that is
now on a branch as it preserves the full optimization of
check-in [e130319317e76119].

when the LHS of an OR operator contains an error and the RHS contains an IN
operator.
