Before this change, a query like `SELECT col_double FROM t WHERE col_double > 2.0 OR col_double < 5.0` would return NaN values in the result, which is incorrect. That was caused by OR-predicate incorrectly translated to Domain. The union of domains: (col_double > 2.0) and (col_double < 5.0), neither accepting NaN, resulted in domain "not null", accepting NaN. The remaining expression was simplified to TRUE. The issue was fixed by returning the original predicate as the remaining expression.
