Active development happens in Intel's tree, and is slowly being merged 
upstream.  Eventually, Clang will have full OpenMP 4 support, but Intel's tree 
will have it first and there is likely to be a lag before it makes it into 
mainline clang.

As such, it would make sense to have a port as a stop-gap until it is ready.
