Remove target specifier from new tests Hopefully fix the remaining bot failure from r254927. Remove target specification since it shouldn't be needed, and this causes an error when trying to check the pass execution structure in test/CodeGen/thinlto_backend.c on non-x86 arches. llvm-svn: 254940

[ThinLTO] Option to invoke ThinLTO backend passes and importing Summary: Adds new option -fthinlto-index=<file> to invoke the LTO pipeline along with function importing via clang using the supplied function summary index file. This supports invoking the parallel ThinLTO backend processes in a distributed build environment via clang. Additionally, this causes the module linker to be invoked on the bitcode file being compiled to perform any necessary promotion and renaming of locals that are exported via the function summary index file. Add a couple tests that confirm we get expected errors when we try to use the new option on a file that isn't bitcode, or specify an invalid index file. The tests also confirm that we trigger the expected function import pass.

[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.
