[PATCH] D90646: [clang] Add warning when `-include-pch` is passed multiple times

Fair question! I think this case is a bit different since it's quite subtle. The strange thing here is that the header you're intending to provide a pch for can still be read successfully, but not getting the benefits of the pch that you were expecting without knowing about it.
