It looks like this commit breaks the following buildbots: [sanitizer-ppc64le-linux](https://lab.llvm.org/buildbot/#/builders/72) build no. [1522](https://lab.llvm.org/buildbot/#/builders/72/builds/1522) and [sanitizer-ppc64be-linux](https://lab.llvm.org/buildbot/#/builders/109) build no. [1249](https://lab.llvm.org/buildbot/#/builders/109/builds/1249). I will attempt to isolate and provide more information about the failure but could you take a look and provide a fix as soon as possible or revert if the fix will take too long.
