[cfe-dev] Ongoing Windows bot failures after r339307

[via cfe-dev]

It looks like a couple of bots are having issues after this patch;
they're getting ~270 test failures.  I replied to the commit email
but got no response.  The bots I'm seeing fail are:

llvm-clang-x86_64-expensive-checks-win
clang-x64-ninja-win7  (stage 1)

My guess is they need to rerun cmake (& delete CMakeCache.txt first,
if not the entire build tree).  That worked in my local builds.

Thanks,
