clang-p2996/llvm/test/CodeGen/AMDGPU/amdgpu-codegenprepare-fold-binop-select.ll
Matt Arsenault 8cc6c2e80f AMDGPU: Migrate more tests away from undef (#131314) 
andorbitset.ll is interesting since it directly depends on the
difference between poison and undef. Not sure it's useful to keep
the version using poison, I assume none of this code makes it to
codegen.

si-spill-cf.ll was also a nasty case, which I doubt has been reproducing
its original issue for a very long time. I had to reclaim an older version,
replace some of the poison uses, and run simplify-cfg. There's a very
slight change in the final CFG with this, but final the output is approximately
the same as it used to be.
