[lworld] Integrated: 8331538: [lworld] Fix array handling code in C2 for JEP 401

[Tobias Hartmann]

This PR contains several fixes to array handling code in C2 to align with the JEP 401 design.

I also fixed an issue with replay compilation where `ArrayStoreData` was not correctly dumped to the file because it's a subtype of `ReceiverTypeData` which was checked first in `ciMethodData::dump_replay_data`.

Thanks,
Tobias
