Good idea, Ivan. 

The mips and ppc64le builders haven't rebuilt with this yet.
http://lab.llvm.org:8011/builders/llvm-mips-linux
http://lab.llvm.org:8011/builders/clang-ppc64le-linux-multistage <http://lab.llvm.org:8011/builders/clang-ppc64le-linux-multistage>

The freebsd builder rebuilt but provided no new output. Exit code -11 is presumably SIGSEGV.

One of the x86_64 builders has a result:
