Thanks - I reverted with 43ae4b62b267 <https://reviews.llvm.org/rG43ae4b62b2671cf73e691c0b53324cd39405cd51>.
It's unlikely that I will be able to investigate those diffs in the near term, so hopefully someone else can commandeer/edit this patch and update D144045 <https://reviews.llvm.org/D144045>.
