[PATCH] D60226: [ThinLTO] Fix ThinLTOCodegenerator to export llvm.used symbols

[Steven Wu via Phabricator via llvm-commits]

steven_wu added a comment.

Also do note, I did a quick benchmark on thin-link time for libLTO.dylib. thin-link was 2.6s before the change vs. 4.0s after the change. Building IRSymtab during thin-link does introduce non-negligible overhead. It might be possible to build them async in threads to reduce the overhead.
