cc1 should be doing the preprocessed output.  Currently it's in
cppmain.c, but it should be moved to a "c-" file in the front end.
This is all part of the work to make cpplib a proper library.
If cc1 is doing the preprocessed output, it's easy for it to dump
whatever it wants in there.

Handling the preprocessed input (with extra lines like yours) is a
little harder, but should be easy once we read a token line at a
time.
