parse tree. This affects debugging builds only and is a no-op for production
builds.

would leave both EP_InnerON and EP_OuterON constraints on the same join term.

so that the whole lot can be copied all at once. Faster and smaller code.

seems to work the same as PG. The code is chaos, however, and needs some
cleanup.

only.

an IdList object to store an Expr pointer together with each name.

"RightJoin" in the former name do not lead readers to believe that this has
something to do with RIGHT JOINs in particular.

the code to compute the unmatched rows for the RIGHT JOIN has not yet been
added, so the result of a RIGHT JOIN is currently the same as an INNER JOIN.

No changes to deliverable builds. Rename SQLITE_ENABLE_SELECTTRACE to
SQLITE_ENABLE_TREETRACE in ctime.c.

release builds.

Expr.w.iOfst field. This is done with the idea of providing offset
results for sqlite3_error_offset() for a more kinds of errors, though that
part is not yet implemented.

terms originating in the ON/USING clause, as demonstrated by
[forum:/forumpost/6cf3bb457c3f4685|forum post 6cf3bb457c3f4685]. This
check-in disables that optimization for ON/USING terms. Also improve the
TreeView display for the resulting "true"/"false" nodes to show that they
originate from the ON/USING clause. Add a testcase() to the other optimization
to show that it can still be used for ON/USING terms.

from an UPDATE where the initial term is omitted. This can happen during a
UNION ALL query flattening while processing a virtual table update in which
the first term of the vector is repeated.

to the number of columns in the vector. This is not strictly necessary. It
just simplifies the state description and make the code easier to reason about.

Also fix an assert() that was failing due to the recent TK_ERROR addition.
