Summary: Adds the following two options to lld-link: -thinlto-prefix-replace: allows replacing a prefix in paths generated for ThinLTO. This can be used to ensure index files and native object files are stored in unique directories, allowing multiple distributed ThinLTO links to proceed concurrently. -thinlto-object-suffix-replace: allows replacing a suffix in object file paths involved in ThinLTO. This allows minimized index files to be used for the thin link while storing the paths to the full bitcode files for subsequent steps (code generation and final linking).
