Description
When --add-exports is specified with "java -XX:AOTMode=create", AOTClassLinking is disabled:

=================================
$ java -cp HelloWorld.jar -XX:AOTMode=record \
       -XX:AOTConfiguration=hw.aotconfig HelloWorld
Hello World
AOTConfiguration recorded: hw.aotconfig

$ java -Xlog:cds -XX:+AOTClassLinking --add-exports java.base/jdk.internal.misc=ALL-UNNAMED \
       -cp HelloWorld.jar -XX:AOTMode=create -XX:AOTCache=hw.aot \
       -XX:AOTConfiguration=hw.aotconfig
[...]
[0.000s][info][cds] optimized module handling: disabled due to incompatible property: jdk.module.addexports=java.base/jdk.internal.misc=ALL-UNNAMED
[...]
[0.456s][info][cds] Number of classes 1043
[0.456s][info][cds] instance classes = 891, aot-linked = 0, inited = 0
=================================

Proposal:

We should support --add-exports for AOT cache, and allow the AOT cache to be used as long as the exact same set of options --add-exports are used during assembly phase and production run.
