Fix evaluation of ISNULL/NOTNULL in OR expressions

Browse Source 
Previously, the `jump_if_condition_is_true` flag was not respected. As a
result, for expressions like <`ISNULL`/`NOTNULL`> `OR` <rhs>, the <rhs>
expression was evaluated even when the left-hand side was true, and its
value was incorrectly used as the final result.
