[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.

PRAGMA foreign_key_check was increased too late for an assert() deep
down inside of sqlite3ExprCode(). So move the size increase a little
earlier.

[https://oss-fuzz.com/testcase-detail/5517690440646656|OSSFuzz]. The
assertion fault is harmless because the assert() checks a condition that
that is harmless if false and the assert() is disabled in production
builds.
