* [ThinLTO] Write TYPE_IDs for types used in functions imported by aliasesVitaly Buka2018-09-191-1/+22
| | | | | | | | | | | | | | | | | | | | | | | Summary: ThinLTO imports alias as a copy of a aliasee, so when we import such functions with type tests we will need type ids used by function. However after D49565 we pick types only during processing of FunctionSummary which is not happening for such aliesees. Example: Unit U1 with a type, a functions F with the type check, and an alias A to the function. Unit U2 with only call to the alias A. In particular, this happens when we use -mconstructor-aliases, which is default. So if c++ unit only creates instance of the class, without calling any other methods it will lack of necessary type ids, which will result in false CFI reports.

* [ThinLTO] Only emit referenced type id records in index filesTeresa Johnson2018-07-191-0/+28
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.
