Alternatively, there is another compiler-defined macro _CET_ENDBR that can
be used.  We can put the following in calling.h:

#ifdef __CET__
#include <cet.h>
#else
#define _CET_ENDBR
#endif

and then use _CET_ENDBR in other files.  How is that?

In the future, in case we have kernel-mode IBT, ENDBR macros are also needed
for other assembly files.

Can we please call it IBT_ENDBR or just ENDBR. CET is a horrible name,
seeing how it is not specific.
