Tracking issue for OpenMP 5.0 support

[h-vetinari]

In #63633, I had asked:

is there an issue somewhere that's tracking the finalization of OpenMP 5.0 support?

Since this hasn't gotten any response in 6+ months, I'm opening an issue now. This is intentionally on a low footprint; other approaches are possible (e.g. libcxx uses individual issues for conformance with C++ features and issues, all of which are tracked in one project).

Going by the points for 5.0 in https://clang.llvm.org/docs/OpenMPSupport.html that aren't marked done yet:
