To avoid this sounding like there's a huge loss: my current testing with this series and the llvm-locstats script on stage2 clang shows no reduction in the "total [variable] availability" number, and a 2% fall in "PC ranges covered", which I would characterise as "most locations preserved with some corner cases still to address".
