Thanks! Yeah, I expect that the MSVC team will regularly need to clean up warnings like these. We hadn't updated our llvm-project submodule in almost a year, so the rate of accumulation over time isn't as high as it might seem.

Merging this now - the failing checks are all the usual unrelated sporadic timeouts/failures and the known failure that I recently fixed.
