d8a295669c Correctly initialize the iSelectId of FROM clause terms that are a self 
join of a reused materialized subquery.  Without this, the EXPLAIN QUERY PLAN
output for the query will identify the subquery using the uninitialized
(and arbitrary) iSelectId.

dc6de47925 The SQLITE_EXTRA_IFNULLROW compile-time option causes OP_IfNullRow opcodes 
to be issued for references to the right-hand side table of *any* flattened
join, not just LEFT JOINs.  This puts extra stress on the OP_IfNUllRow opcodes
for testing purposes.
