[PATCH] D31027: [ThinLTO] Add support for emitting minimized bitcode for thin link

[Teresa Johnson via Phabricator via llvm-commits]

I did some testing with this change. The cumulative size of the bitcode files that need to be sent to the remote node performing the thin link drops from 20G to 2.5G. I also did a sanity check that all 20K+ individual index files and .imports files produced when thin linking with the original .o files and with the minimized thin link files were identical (also tested here in the new gold test, but I wanted an additional sanity check).
