RFR: 8258912: Remove JVM options CountJNICalls and CountJVMCalls

Tue Jan 12 15:23:11 UTC 2021

Please review this change to remove the old non-product JVM -XX flags CountRuntimeCalls, CountJNICalls, CountJVMCalls, and CountRemovableExceptions.  Additionally, this change removes non-product flag WarnOnStalledSpinLock because, as a result of this change, it is no longer used.

The change was tested with Mach5 tiers 1-2 on Linux, Mac OS, and Windows, and tiers 3-5 on Linux x64.

Thanks, Harold
