> As I understand it, we want to uncover these bugs in passes that use value tracking because it signals a potential efficiency improvement for them when dealing with dead code or other corner cases.

We don't actually have a solution to reliably avoid analyzing dead code... see the discussion on https://reviews.llvm.org/D34135.
