Whenever -fmodule-name=top_level_module name is parsed, and clang actually tries to import top_level_module, the headers are imported textually and the module isn't actually built. However, the dependency scanner could still record it as a potential dependency if the module was reimported and thus recorded by the preprocessor callbacks. This patch avoids collecting this kind of module as a dependency by verifying that we don't collect top level modules without actual PCM files.
