This is somewhat scary. The code is a bit convoluted, which is why I
was cleaning it up on the way to also being lazy about variables and
aliases.

Have you ever managed to get a reduced testcase? In my experience
linker bug are really easy to reduce by running delta on the list of
input functions and using llvm-extract to keep only the ones delta
selected.
