7f414c0c0c Check-in [fa792714ae62fa98] is incorrect. Add a test case to refute it and 
also a fix to make it right. 
Then add an alternative fix to ticket [df46dfb631f75694] in which
all ephemeral tables used as the RHS of an IN operator be index btrees
and never table btrees so that they can always be reused.

table can be reused for both cases.

bc0a55cf0b Check-in [fa792714ae62fa980] is not a valid fix for ticket 
[df46dfb631f75694], as the new test case in this check-in demonstrates.
The fix here causes test cases for the [df46dfb631f75694] bug to fail
again, so this check-in is on a branch.  A new fix is needed for
[df46dfb631f75694].

is originally UTF8 and has to be converted to UTF16 to match the database
file and that conversion causes the string to become shorter and cross

that we have been so far unable to reproduce.

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].
