[lworld] RFR: 8355076: [lworld] Incorrect declared_nonstatic_fields computation [v3]

[Quan Anh Mai]

> Hi,
> 
> This patch fixes the computation of declared_nonstatic_fields if the super class contains flat fields. Note that due to [JDK-8354322](https://bugs.openjdk.org/browse/JDK-8354322) such cases are not present at the moment.
> 
> Please kindly review, thanks a lot.
