It seems to have be failing for aarch64 since it was introduced:

http://lab.llvm.org:8011/builders/clang-cmake-aarch64-full/builds/5509 is failing and covers the range which added this test
http://lab.llvm.org:8011/waterfall?show=clang-cmake-aarch64-full shows that the test has been failing since that build onwards, except for build 5514 which was interrupted before stage2 tests were run.
