When a framework can be found at a new location, all references to it in the module cache become outdated. When we try to load such outdated .pcm file, we shouldn't change any already loaded and processed modules. If `Module` has `ASTFile`, it means we've read its AST block already and it is too late to undo that. If `ASTFile` is `None`, there is no value in setting it to `None` again. So we don't reset `ASTFile` in `ModuleManager::removeModules` at all. rdar://97216258 Differential Revision: https://reviews.llvm.org/D134249
