roll clang 138187:138500

Also pass --disable-threads and --disable-pthreads to configure, for goma.

Also modify the script to try to download prebuilt binaries first. This is faster,
and makes sure the bots use the exact same binary as goma. The binaries are
downloaded from http://commondatastorage.googleapis.com/chromium-browser-clang/index.html

Also add a script that packages a clang build up into a tgz for uploading with
gsutil, based on code by ukai@.

Finally, if the svn checkout fails, remove the destination directory and try
again (for bots that have a checkout from before we had an internal llvm svn
mirror).
