[LTO] Make processing of combined module more consistent Summary: 1. Use stream 0 only for combined module. Previously if combined module was not processes ThinLTO used the stream for own output. However small changes in input, could trigger combined module and shuffle outputs making life of llvm::LTO harder. 2. Always process combined module and write output to stream 0. Processing empty combined module is cheap and allows llvm::LTO users to avoid implementing processing which is already done in llvm::LTO.
