Extended Description

Apparently scan-view is broken now:

Traceback (most recent call last):
File "/usr/lib/llvm/12/bin/scan-view", line 150, in
main()
File "/usr/lib/llvm/12/bin/scan-view", line 147, in main
run(port, args, args.root)
File "/usr/lib/llvm/12/bin/scan-view", line 74, in run
import ScanView
File "/usr/lib/llvm/12/bin/../share/scan-view/ScanView.py", line 29, in
import Reporter
ModuleNotFoundError: No module named 'Reporter'

I'm surprised we don't cover it with regression tests.

The fix's apparently in https://reviews.llvm.org/D96367
