New candidate JEP: 515: Ahead-of-Time Method Profiling

[Mark Reinhold]

https://openjdk.org/jeps/515

  Summary: Improve warmup time by making method-execution profiles from
  a previous run of an application instantly available, when the HotSpot
  Java Virtual Machine starts.  This will enable the JIT compiler to
  generate native code immediately upon application startup, rather than
  having to wait for profiles to be collected.
