Performance improvements to the (debug-use only) Mem.pScopyFrom logic, resulting

in about 8x faster performance under -DSQLITE_DEBUG for the query in from

or 2 or more arguments, respectively. This saves space in the built-in

For the purpose of the query planner heuristic added by [38db9b5c83], a query
...
should only count as a star query if the fact tables are connected to the
dimension table by an INNER JOIN. If a LEFT JOIN is used, then the fact
tables are constrained to be in inner loops anyhow and so the heuristic does
not make any sense. But it does interfere with AUTOMATIC index creation, which
causes the performance regression reported by
[forum:/forumpost/d87570a145599033|forum post d87570a1455].
