785097da6b A bug report coming from from Firefox 
([https://bugzilla.mozilla.org/show_bug.cgi?id=840377])
describes an infinite recursion.  We are unable to reproduce the problem.
Nevertheless, this check-in should prevent the problem from ever occurring
again.

c3e552ff5c Allow the "a=?1 OR a=?2" to "a IN (?1,?2)" transformation to work on virtual 
tables again.  This was formerly restricted because virtual tables could not
optimize IN terms.  (See check-in [fad88e71cf195e].)  But IN terms are now
used by virtual tables (as of check-in [3d65c70343]) so the restriction can
now be removed.

itself inside parentheses.  Generate code as if the parentheses did not
exist, rather than the old behavior of manifesting the parenthesized table
into a transient table.  Also, tag every FROM-clause SELECT subquery that is
generated by a parenthesized FROM-clause expression using the SF_NestedFrom
flag.  The new SF_NestedFrom flag is not yet used for anything.
