When preprocessing with -frewrite-imports and -fmodule-file=, do not pass all
modules to preprocessing of nested .pcm files. Making those module files available results in loading more .pcm files than necessary, and potentially in misbehavior if a module makes itself visible during its own compilation (as parts of that module that have not yet been processed would then become visible). llvm-svn: 306320
