Reinsert two NEVER() macros for b-tree branches that were previously needed for [b6a82f3c3b9d89fd] but which are now obsolete due to [73f0036f045bf371]. Later: dbsqlfuzz quickly found new cases for which those two branches are needed. The new test cases have been added to TH3. (Closed-Leaf check-in: 3065dadb user: drh tags: backout)

When doing a push-down of a WHERE clause into an aggregate subquery that has no FROM clause, do not convert the WHERE clause into a HAVING clause as should normally be done for an aggregate, but leave it as a WHERE clause. We will use a different approach to address forum post 1a7fea4651. (Leaf check-in: 1f575841 user: drh tags: backout)
