[lworld] RFR: 8326839: [lworld] Aarch64 interpreter still prevents new bytecode to be used with value classes

[Frederic Parain]

Small fix on aarch64 template interpreter: bytecode `new` was still rejecting value classes but this behavior is now allowed by JEP 401. The issue occurred only when `new` operates on a resolved constant pool entry.
