The patch is the same except for the addition of a new test for the issue that required reverting the dependent llvm commit. --Original Commit Message-- Pass down the -flto option to the -cc1 job, and from there into the CodeGenOptions and onto the PassManagerBuilder. This enables gating the new EliminateAvailableExternally module pass on whether we are preparing for LTO. If we are preparing for LTO (e.g. a -flto -c compile), the new pass is not included as we want to preserve available externally functions for possible link time inlining. llvm-svn: 241467
