> Is it possible you have LLVM and Clang checked out at different revisions? That's a common source of weird behavior, particularly in CodeGen tests.

Unfortunately no - when I don't specifically don't set the type trait kind of `__alignof` to `UETT_PreferredAlignOf`, and remove the code in `AlignOfType` to differentiate between `PreferredAlignOf` and `AlignOf`, all the tests pass again.
