@parrt Another C++ patch ready for merge.

@mike-lischke could you guys resolve the conflict? thanks!

Fixed conflict.

@jcking Thanks!

@parrt The C++ parser tests just take too long and always time out now, it seems :-( At least this is what CircleCI says. Github actions just have a red cross saying the action failed (not exactly helping...).

Otherwise the patch looks fine for merge.

Is it possible to improve the performance of C++ compilation by any way? I've noticed it's slow on my local machine as well.

Also, maybe it makes sense to request a more advanced tariff plan for ANTLR project for free because it's valuable and free project.

It's slow because it does the worst thing you can do to a C++ project: frequent rebuilds. That's not an issue with script languages or more modern languages. Improving that would require to restructure the way the tests run, which at the time I suggested that the last time wasn't really an option.

A better tariff would certainly help.

Yes, something like that. I can imagine how it could work for C# (the second slowest language after C++ but even so much faster): use dynamic compilation, but can not for C++.

I am thinking about rebuilding the test rig so I will split apart the parsing test so that C++ can pass.
