--- Comment #14 from Jeremy Morse <jeremy.morse.llvm at gmail.com> ---
placeDbgValues was significantly limited in 00e238896c, and it looks like the
patch is sticking. There's still some work to be done with debug
use-before-defs (which are already an error-state), but the vast majority of
faulty behaviour should now be fixed. Horray!

(I'll clean up the other tickets this depends on, which fall into the category
of "things that Jeremy saw and bothered him", at some other time).
