GCC 6.2/7.0 vs. LLVM Clang 3.9/4.0 SVN Compiler Performance

Earlier this week I published some GCC 5.4 vs. GCC 6.2 vs. GCC 7.0 SVN development benchmarks with a Core i7 6800K Broadwell-E system. For those curious how the LLVM Clang compiler stack is comparing, here are some tests on the same system when running fresh benchmarks of LLVM Clang 3.9 as well as LLVM Clang 4.0 SVN.
