[ThinLTO] Optionally ignore empty index file Summary: In order to simplify distributed build system integration, where actions may be scheduled before the Thin Link which determines the list of objects selected by the linker. The gold plugin currently will emit 0-sized index files for objects not selected by the link, to enable checking for expected output files by the build system. If the build system then schedules a backend action for these bitcode files, we want to be able to fall back to normal compilation instead of failing. Fallback is enabled under an option in LLVM (D28410), in which case a nullptr is returned from llvm::getModuleSummaryIndexForFile. Clang can just proceed with non-ThinLTO compilation in that case. I am investigating whether this can be addressed in our build system, but that is a longer term fix and so this enables a workaround in the meantime.

[ThinLTO] Pass -save-temps to LTO backend for distributed ThinLTO builds Summary: The clang driver option -save-temps was not passed to the LTO config, so when invoking the ThinLTO backends via clang during distributed builds there was no way to get LTO to save temp files. Getting this to work with ThinLTO distributed builds also required changing the driver to avoid a separate compile step to emit unoptimized bitcode when the input was already bitcode under -save-temps. Not only is this unnecessary in general, it is problematic for ThinLTO backends since the temporary bitcode file to the backend would not match the module path in the combined index, leading to incorrect ThinLTO backend index-based optimizations.
