I presume all API tests on Windows are compiling against MSVC STL when compiled on Windows (it has nothing else to use). If you're wondering whether there's a good way to detect that is the case, yeah, that might be tricky.

For number 2, I'm not into the idea of changing the existing bot to build everything against libcxx, but if we can enable the runtime and then libcxx specific tests will be run as well, that's fine. Windows is supported and tested for libcxx as long as clang/clang-cl is the compiler, which we use already on the bot.
