cc1obj is the Objective C compiler.  cc1plus is the C++ compiler.  cc1
is the C comipler.  Currently they are separate programs.  Currently
they include a preprocessor, but the preprocessor can also be run in a
separate step, which is what this option does.  It is possible that in
the future cc1obj, cc1plus, cc1, and others, will be merged into a
single program.
