Teresa Johnson a7d69b86de [ThinLTO] Only emit referenced type id records in index files ... Summary: Currently all type ids are emitted into the index file when it is written. For distributed ThinLTO, that meant that all type ids were being duplicated into every single distributed index file, regardless of whether they were referenced, leading to huge amounts of unnecessary duplication and size bloat. Keep track of the type id GUIDs actually referenced by the GV summary records being emitted, and only emit those type IDs. Add a new test, and fix test/Assembler/thinlto-summary.ll so that all type ids are referenced to prevent deletion in that test.
