One of the reasons of the in-process cc1 was the debuggability. If we can compile several TUs in-process, why not doing it?

As for build times, we found that even with the clean up, in-process+clean-up is faster than out-of-process+disable-free. That is, on Windows and in the context of the `llvm-buildozer` app I've presented at the LLVM conf., where all the TUs for a project are compiled in the same process (meaning there's a clean up after each TU).

Any other issues you were seeing with this current approach?
