[PATCH] D126796: [clang][driver] adds `-print-diagnostics`

[Christopher Di Bella via Phabricator via cfe-commits]

cjdb added a comment.

I haven't added a test because I'm not sure how we can reasonably test this without keeping a file that holds all the warnings and using FileCheck. I'm okay with that, but want to make sure it's the best thing to do.
