In Linux, the current implementation of swift-autolink-extract does not support LLVM IR files resulting from using LTO. If one tries to build LLVM using LTO and then try to link one of the targets that use `swiftc` to link, but link against LLVM object files (like `swift-plugin-server`), `swift-autolink-extract` will fail saying that some object files are not valid. To deal with LLVM IR files correctly, create and pass a `llvm::LLVMContext` around, which allows the APIs in `llvm::object` to read LLVM IR files. Additionally, handle the case of `IRObjectFile` when extracting, but perform no action.
