RFR/A: 8234863: Increase default value of MaxInlineLevel

[Hohensee, Paul]

I’d like to backport this patch, which increases the default value of MaxInlineDepth from 9 to 15. Since it changes behavior, it requires a backport CSR.

Original JBS issue: https://bugs.openjdk.java.net/browse/JDK-8234863
Original commit: https://hg.openjdk.java.net/jdk/jdk/rev/3c8af950e849
Original CSR: https://bugs.openjdk.java.net/browse/JDK-8235336

Backport JBS issue: https://bugs.openjdk.java.net/browse/JDK-8256164
Backport CSR: https://bugs.openjdk.java.net/browse/JDK-8256165

The patch is clean, so I’ve tagged the issue with jdk11u-fix-request. The CSR needs review before we can proceed.

The patch has been in use internally at Amazon with no reliability, footprint, or performance issues. I’ve run tier1-3 tests successfully.

Thanks,
Paul
