As we have discussed in https://reviews.llvm.org/D127284 we would like to phase out `enableIncrementalProcesing` and use a better integrated option.

https://reviews.llvm.org/D127284 introduces a `LangOpt` called `IncrementalExtensions`, however, we also have a `TU_Incremental` kind. I am not entirely sure when we should use that because generally most of our actions (even if we pass `-fincremental-extensions`) we still get `TU_Complete`.

@aaron.ballman, @rsmith, do you have an idea how to harmonize this?
