The `SYCLIsDevice` and `SYCLIsHost` members of `LangOpt` are pre-existing and referenced from numerous source files. I'm not going to change them as part of this PR. You are welcome to submit a PR to change them if you like. Otherwise, we can investigate changing them as part of a future offload unification effort.
