`-XX:+AOTClassLinking` requires the CDS archived full module graph (FMG). - Before this PR, when `--add-export` is specified, FMG is disabled, so AOT caches created with `-XX:+AOTClassLinking` cannot be loaded. - After this PR, if the exact same `--add-export` flags as specified across the training/assembly/production phases, the FMG can be used, so we can use so AOT caches created with `-XX:+AOTClassLinking`.
The change itself is straight-forward: just remember the `--add-export` flags specified during AOT cache creation, and check the exact same ones are used during the production run. I did a fair amount of refactoring to change the "exact options specified" checks in modules.cpp, so more such options can be easily added in the future (we need to handle `--add-reads` and `--add-opens` in future RFEs).
