Stop relying on `cl::opt` to pass along the driver's decision to preserve use-lists. Create a new `-cc1` option called `-emit-llvm-uselists` that does the right thing (when -emit-llvm-bc). Note that despite its generic name, it *doesn't* do the right thing when -emit-llvm (LLVM assembly) yet. I'll hook that up soon. This doesn't really change the behaviour of the driver. The default is still to preserve use-lists for `clang -emit-llvm` and `clang -save-temps`, and nothing else. But it stops relying on global state (and also is a nicer interface for hackers using `clang -cc1`). llvm-svn: 234962
