OpenMP Language Changes in Clang

-`status <https://github.com/clang-omp/clang/wiki/Status-of-supported-OpenMP-constructs>_`
-LLVM’s OpenMP runtime library, originally developed by Intel, has been modified to work on ARM, PowerPC,
-as well as X86. The Runtime Library's compatibility with GCC 4.9 is improved
-- missed entry points added, Barrier and fork/join code improved, one more type of barrier enabled.
-Support for ppc64le architecture is now available and automatically detected when using cmake system.
-Using makefile the new "ppc64le" arch type is available.
