pcc added a comment.

This is testing a clang feature that reads IR and runs the ThinLTO backend. This feature is part of ThinLTO's distributed build support (search for "Distributed Build Support" in http://blog.llvm.org/2016/06/thinlto-scalable-and-incremental-lto.html).

In a future change I want to replace the clang-side code here with a client of a new LTO interface that takes IR and produces object files (see http://reviews.llvm.org/D21545). So I think testing the object file is the right approach here.
