Restore "Resolution-based LTO API." This restores commit r278330, with fixes for a few bot failures: - Fix a late change I had made to the save temps output file that I missed due to existing files sitting on my disk - Fix a bunch of Windows bot failures with "ambiguous call to overloaded function" due to confusion between llvm::make_unique vs std::make_unique (preface the new make_unique calls with "llvm::") - Attempt to fix a modules bot failure by adding a missing include to LTO/Config.h. Original change: Resolution-based LTO API. Summary: This introduces a resolution-based LTO API. The main advantage of this API over existing APIs is that it allows the linker to supply a resolution for each symbol in each object, rather than the combined object as a whole. This will become increasingly important for use cases such as ThinLTO which require us to process symbol resolutions in a more complicated way than just adjusting linkage. Patch by Peter Collingbourne.
