Spring Optimize sortPostProcessors() in PostProcessorRegistrationDelegate

Size equal to 0 or 1 can return directly

private static void sortPostProcessors(List<?> postProcessors, ConfigurableListableBeanFactory beanFactory) {
        Comparator<Object> comparatorToUse = null;
        if (beanFactory instanceof DefaultListableBeanFactory) {
            comparatorToUse = ((DefaultListableBeanFactory) beanFactory).getDependencyComparator();
        }
        if (comparatorToUse == null) {
            comparatorToUse = OrderComparator.INSTANCE;
        }
        postProcessors.sort(comparatorToUse);
    }

Good catch. We'll optimize this in 5.2.6.

It make code ugly, is it worthy?

@quaff, We have implemented similar optimizations recently. See #24617 for details.
