[Renato Golin via llvm-commits]

Hi Joerg,

This is an XPASS, and looks related to your commit, so maybe all we
need to do is to mark it as a pass?

http://lab.llvm.org:8011/builders/clang-cmake-aarch64-39vma/builds/5176

http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15/builds/5512

http://lab.llvm.org:8011/builders/clang-cmake-aarch64-full/builds/1622

If it's related, feel free to just remove the xfail on arm/aarch64.

Thanks!
