For example, when --fuzzing is off, %OptimizeFunctionOnNextCall now crashes when given a non-function argument. The following behaviors remain unchanged for now: - %DeoptimizeFunction continues to do nothing if the function is not optimized. - %DeoptimizeNow continues to do nothing if the top-most JS function is not optimized. - %OptimizeOSR continues to do nothing if the function already has optimized code.
