Add --plugin-opt=emit-llvm option.
`--plugin-opt=emit-llvm` is an option for LTO. It makes the linker to
combine all bitcode files and write the result to an output file without
doing codegen. Gold LTO plugin has this option.
This option is being used for some post-link code analysis tools that
have to see a whole program but don't need to see them in the native
machine code.
