JDK-8317278 - JVM implementation of value classes and objects
Description
The jasm and jdis tools used to run tests require enhancement to support the JVM changes of Value Classes and Objects, as described in JDK-8317278.

There are three class file changes:

1) The ACC_IDENTITY flag on class declarations, which replaces ACC_SUPER
2) The ACC_STRICT flag on fields (previously used on methods in legacy classes)
3) The LoadableDescriptors attribute, which contains a list of Utf8 descriptors

This task can be completed when the jtreg version used for mainline development includes a version of jasm that supports the new features.
Comments
Yeah, I'm not sure how to file it. Put it in 'tools' for now. The tools themselves are handled by CODETOOLS-7903806. This task is done when the dependencies are updated—e.g., updated asmtools is included with jtreg, and udated jtreg is used in the repo.

[~dlsmith] I'm not sure why this is set on infrastructure/build. The description give no indication that anything needs to be adapted in the build system.
