Missing Openmp support in clang 11

[victor-zou]

I an using a latest version gcc10 and clang11. I find there is no omp.h and the corresponding libomp lib in the package. So, is there some issue stopping the authoring to release the clang togather with the openmp, or I can wait for this feature in a future not far away?

Main focus of winlibs is on GCC, and libgomp is included as provided by GCC. LLVM/Clang was built using GCC standard libraries, so that is LLVM's libomp is not included. I'm not sure if adding this would cause any kind of conflict. I will keep this ticket open and if I find the time I will look into compiling LLVM's OpenMP.

If so, it would be very greatly appreciated :)
