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

FWIW, this change causes https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=246630, see in particular https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=246630#c18.

For some reason, not spawning a new process for the cc1 stage can lead to non-reproducible output. The exact cause is not known yet.
