RFR: 8355003: Implement Ahead-of-Time Method Profiling [v2]

[Igor Veresov]

> Improve warm-up time by making profile data from a previous run of an application instantly available, when the HotSpot Java Virtual Machine starts. Specifically, enhance the [AOT cache](https://openjdk.org/jeps/483) to store method execution profiles from training runs, reducing profiling delays in subsequent production runs.
> 
> More details in the JEP: https://bugs.openjdk.org/browse/JDK-8325147

Igor Veresov has updated the pull request incrementally with two additional commits since the last revision:

 - Remove the workaround of setting AOTRecordTraining during assembly
