Well, it was expected. However, I didn't want to mess this refactoring with OpenCL C 3.0 support at first.

I already do have some progress in this direction: https://reviews.llvm.org/D92277. We can differentiate between core and optional features by the defining them appropriately in `OpenCLExtensions.def`. Note that this also removes duplication of `OpenCLOptions` so we can query all features/extensions from `TargetInfo` directly. This will also allow simplifying `OpenCLOptions` in future
