> When creating the AOT configuration file or the AOT cache file, we load a few "AOT tooling" classes that are not needed in the production run. This PR adds an API for filtering out such classes to reduce footprint.
>
> In addition, with the upcoming [JDK-8325147](https://bugs.openjdk.org/browse/JDK-8325147) (Ahead-of-Time Method Profiling), profiles for the tooling classes will be also be excluded. This will prevent the JVM from compiling methods at start-up which aren't going to be used.
