> 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.

Ioi Lam has updated the pull request with a new target base due to a merge or a rebase. The pull request now contains four commits:

 - Refactored CollectClassesForLinking for simplification
 - Merge branch 'master' into 8353014-exclude-tooling-classes-from-aot-cache
 - Reverted some fixes in systemDictionaryShared.cpp that causes test failures
 - 8353014: Exclude AOT tooling classes from AOT cache
