preprocessed repro

Chromium's ThreadLocalStorageTest.TLSDestructors fails when built for 64-bit
with clang-cl. Relevant file:

https://code.google.com/p/chromium/codesearch#chromium/src/base/threading/thread_local_storage_win.cc&sq=package:chromium

Preprocessed source attached.

Running

  editbin /section:.CRT$XLB,!w
out64\Release_x64\obj\base\threading\base.thread_local_storage_win.obj

and then relinking the binary fixes this, so something in that area is wrong.
