openmp support in llvm3.4.2?

Hello Richard,
Unfortunatelly we did not ported clang-omp to 3.4.2. But you can do it yourself, since there are not too much differences between clang 3.4.0 and 3.4.2.
The latests git version with 3.4.0 is 2f4be128d1f19348ec815e5f49f05b61453755d2 for clang/clang-omp branch.
