7cd5e856e5 Fix the query flattener optimization so that it preserve the "SF_Compound" 
bit when flattening a compound subquery into a non-compound outer query.
Failure to preserve that bit could allow subsequent flattenings which are
not valid. Fix for ticket [c41afac34f15781fe09cd].

3e4f6c43b8 A minor variation on check-in [1685610ef8e0dc] which (hopefully) makes the 
logic a little easier to follow.  Also disallows the use of the double-quoted
string hack in the query expression used for VACUUM INTO, which is not
strictly required, but moves us toward the goal of disallowing the double-quoted
string hack everywhere.
