invalid subquery from causing problems downstream. If an error is found
while analyzing a subquery expression, change the expression to TK_ERROR
so inhibit further processing on that expression.

generated twice. But for some subqueries, generating code off of the same
tree twice causes problems. So now MULTI-INDEX OR makes a copy of the
sub-expressions it uses to avoid code-generating them more than once.

function deletes that happen inside virtual-table destructors that are run
when a database connection is closing do not create new tombstones in the
function table after the function table has already been purged.

speeds them up depending on the query. And (see
[forum:/forumpost/8692d94725|forum post 8692d94725]) it sometimes results in
an incorrect answer. We may come back and revisit this optimization later,
but for now it seems best just to disable it.
