[PATCH] D23466: ADT: Remove UB in ilist (and use a circular linked list)

[Hans Wennborg via llvm-commits]

hans added a comment.

I tried this out on Windows.

Some tests are currently red with ToT: http://lab.llvm.org:8011/builders/clang-x86-win2008-selfhost/builds/9727
On my machine, only CodeGen/AMDGPU/amdgpu.private-memory.ll fails.

When I apply this patch, CodeGen/AMDGPU/predicate-dp4.ll starts hanging, but that's the only change I get.
