LLVM Clang Performance Matching The GCC Compiler On AMD Threadripper 3960X

Off to the races, we were seeing LLVM Clang at the end of 2019 being quite competitive with GCC on this latest-generation AMD workstation CPU. The GCC 9 vs. GCC 10 performance was largely the same but unfortunately the release build of LLVM Clang Git was pointing to performance regressions compared to LLVM Clang 9.0 stable. We've also seen Clang 10 running slower than Clang 9 on other systems and will have those additional results out in the coming days.

In the TSCP chess benchmark, Clang was much faster than GCC.
