Hi Chad,

Thank you for catching and reverting this. I started looking at this and I can reproduce this locally.

Thanks,
Nadav

Hi Nadav,
To allow our internal buildbots to make forward progress, I reverted this in revision 142604.

Looks like on of the tests in VMCore (test 5675) is falling into an infinite loop.  I was able to reproduce this locally.

Nadav,
            This seems to be causing widespread bot failures. Can you jump on this right away, or revert?

On lab.llvm.org<http://lab.llvm.org/> these are failing:
clang-x86_64-debian
clang-x86_64-debian-selfhost-rel
clang-X86_64-freebsd
llvm-x86_64-linux
llvm-i686-debian
llvm-x86_64-ubuntu
llvm-gcc-i386-linux-selfhost

And most of my bots are gated on a bot that is failing.
