Subject: Add ability to limit amount of preprocessing done on source

The cc.preprocessed variable can be 'none' (not preprocessed), 'includes' (no
depends on preprocessor, e.g., #ifdef, etc), and 'all' (the source is fully
preprocessed). Note that for 'all' the source can still contain comments and
line continuations.
