The current state of C++20 support regarding compilers and headers is a bit confusing: GCC 10 and its accompanying headers partially implement C++20, and Clang++ 10...12 has partial C++20 support, too. But there is some stuff in GCC's headers that confuses Clang++, mostly regarding comparison operators. Because of this, we can't use Clang-based tools in C++20 mode, so we fall back to C++17. This isn't that bad, lots of interesting C++20 stuff is still missing, anyway. Change-Id: I8ab8f86118ab5963cf91dd479b9d34e478f8ee37
