Init-order and use-after-return modes can currently be enabled by runtime flags. use-after-scope mode is not really working at the moment. The only problem I see is that users won't be able to disable extra instrumentation for init-order and use-after-scope by a top-level Clang flag. But this instrumentation was implicitly enabled for quite a while and we didn't hear from users hurt by it. llvm-svn: 210924
