RFR(XS): 8140721: ProfilerNumberOf*Methods flags should be diagnostic

[Rahul Raghavan]

Hi,

Please review the following patch for JDK-8140721.

- Bug: https://bugs.openjdk.java.net/browse/JDK-8140721
- Webrev: http://cr.openjdk.java.net/~rraghavan/8140721/webrev.00/

- Changed following four flags from 'develop' to 'diagnostic' -
    [ProfilerNumberOfInterpretedMethods, ProfilerNumberOfCompiledMethods, ProfilerNumberOfStubMethods, ProfilerNumberOfRuntimeStubNodes]

- No issues with JPRT (-testset hotspot).
- Confirmed no issues, expected behavior with the change for small unit tests.
  (for debug/release VM with combinations of the flags, UnlockDiagnosticVMOptions usages)
- Found no existing tests using the flags to be changed.

Thanks,
Rahul
