SYCL patches upstream status

Current implementation includes patches to two LLVM projects: Clang and LLVM.

In addition to that there is SYCL standard library project, which probably can be contributed with a single patch, so SYCL runtime library patches are not tracked here.

Clang patches

I used following command to create the list of SYCL patches to clang:

git log --before="09-Apr-19" --format=format:"| [%h](https://github.com/intel/llvm/commit/%H) | %an | %s | TBD | |" --no-merges --reverse origin/master..origin/sycl -- clang

To get a new entries for this tables, just update the date for --before="09-Apr-19" and add --since="09-Apr-19" to avoid duplicated entries.
