@ldionne Thanks for reviving, happy to help push this over the finish line. Though would be good to loop @adrian-prantl @kastiglione into this.

The follow-up to this would be to ensure LLDB looks in the right location to auto-load on Linux (and on macOS the SDK, though if i remember correctly we already landed the macOS bit).

Could we `apt-get` LLDB in the Dockerfile? I don't think we need to go out of our way to get top-of-tree LLDB. We're only using the public LLDB API in these data formatters, which shouldn't ever be breaking. Worst case is the formatters will rely on a new LLDB feature, at which point we'd have to bump the required version in Docker
