[PATCH] D76829: [lit] Introduce setup and teardown routines

[Julian Lettner via Phabricator via llvm-commits]

> I personally believe that a more useful feature for lit would be to allow batching sets of RUN commands or something like that. For example, imagine if we could compile all the tests locally and only then execute them on the remote host -- you wouldn't only save the cost of scping N times, you would also save on all the ssh's. That would be a major improvement. To me, trying to just save on copying the inputs is taking the easy way for less benefit, and it's not clear to me this will even work with the upcoming libc++ lit configuration, where each test will require its copy of the inputs.

Without a strong use case from libc++ I would prefer to hold off on this and see if it is still needed after we made the other improvements.
