I plan to split the PR, before I move it to `Open` state. In this `Draft` I'm adding some changes to make sure the new format works as expected for SYCL as well.
FYI, I also merged this draft PR to my fork of `intel/llvm` repo and I'm prototyping follow-up changes that will be needed for some SYCL features in `intel/llvm` repo based on new format.
