[ThinLTO] Add an API to trigger file-based API for returning objects to the linker Summary: The motivation is to support better the -object_path_lto option on Darwin. The linker needs to write down the generate object files on disk for later use by lldb or dsymutil (debug info are not present in the final binary). We're moving this into libLTO so that we can be smarter when a cache is enabled and hard-link when possible instead of duplicating the files.
