Hi Chad,

We all got to the same conclusion from different routes. ARM was also
reporting failures and our autoconf self-hosting bot
(http://lab.llvm.org:8011/builders/clang-native-arm-cortex-a15-self-host/builds/1985)
spotted the problem, too.

What I was requesting is that, whomever fixes it, make sure to run a
self-hosting native Clang/LLVM check-all build before committing.

cheers,

PS: The parallel discussion was about the correctness of the patch, so
please don't re-apply without checking, even if it passes all tests.
