Is there a command-line tool that can perform JSON schema validation which is included in a commonly used package that's available in the default package repositories of major Linux distros? If so, we may be able to get away with just requiring that the buildbots have that package installed.

If not, then we'd need to check in such a tool into the LLVM repo (and if it needs building, integrate its build into the build system).

In either case, the tests themselves can take the form of simple lit tests <https://llvm.org/docs/CommandGuide/lit.html> that invoke that tool on some test config files.
