      tools/x86_64: Fix cpuid() inline asm to not clobber stack's red zone
      
      Pushing stuff onto the stack on x86-64 when we do not specify
      -mno-red-zone is unsafe. Since the complicated asm is due to register
      pressure on i386, we simply implement an all-new simpler alternative
      for x86-64.
