// The problem with AVX2 builds on Windows, is that MSVC generates AVX instructions for zeroing memory,
// which is pretty common in our global object constructors. So, we have to use a special object which
// gets initialized before all other global objects, that does the hardware check, and terminates the
// process before main() or any of the other objects are constructed (which would subsequently crash).
