the register was the last instruction in the sequence for the expression, which

prevents the registered that will be recomputed from being cached in the first

2c492061ce Bug fix in the LEFT JOIN strength reduction optimization of 
check-in [dd568c27b1d76563].  The sqlite3ExprImpliesNotNull() routine was
mistakenly assuming that a CASE expression must always be NULL if contained
any reference to a variable that was NULL.
