[8u-dev] Request for enhancement backport approval for CR 8054889 - Compiler team's implementation task

[David Buck]

Hi!

Please consider the following enhancement for approval:

bug report:
https://bugs.openjdk.java.net/browse/JDK-8054889

This is an important serviceability improvement. These new diagnostic 
commands provide us with a supported and safe way to better understand 
what the JIT compiler is doing. I have run all the standard JPRT hotspot 
tests, run the testcases included in the changeset, and manually 
confirmed that the new diagnostic commands work as expected. The change 
itself is extremely small and safe. I believe any risk posed by 
including this in JDK 8 is negligible.

Cheers,
-Buck
