[PATCH] D69825: [Clang][Driver] Re-use the calling process instead of creating a new process for the cc1 invocation

@wenlei Taking a look now.
@hans I remember now why I was re-entering main() in the first iteration of this path. Response files were one reason. And handling /MP was another, which triggers the re-entrance twice (once for CL driver, and once for cc1).
