jansvoboda11 added a comment. I've changed this patch so that the errors and debugging output goes to `DiagnosticsEngine`.
Also, I switched back to the original solution, where we always round-trip when Clang is built certain way (this time not when CMake was configured with `-DLLVM_ENABLE_ASSERTIONS=ON`, but with `-DCLANG_ROUND_TRIP_CC1_ARGS=ON`). The problem with the previous solution (passing `-round-trip-args` from the driver to `-cc1`) is that a lot of tests invoke `-cc1` directly, not through the driver. We want to test round-tripping on such tests as well, but shouldn't pollute them with `-round-trip-args` or force them to go through the driver. I've considered enabling round-tripping through an environment variable, but the problem is that the, the environment variable is not propagated when running lit tests.
