Restore "[ThinLTO] Emit individual index files for distributed backends"
This restores commit r268627: Summary: When launching ThinLTO backends in a distributed build (currently supported in gold via the thinlto-index-only plugin option), emit an individual index file for each backend process as described here: http://lists.llvm.org/pipermail/llvm-dev/2016-April/098272.html ... Differential Revision: http://reviews.llvm.org/D19556 Address msan failures by avoiding std::prev on map.end(), the theory is that this is causing issues due to some known UB problems in __tree. llvm-svn: 269059
