Currently there are (at least) 4 special functions that use unconditional abort/terminate to express that, they are not supposed to be called at runtime, but have to be defined for some reasons:

It's desirable to make them distinct from common noreturn functions, which are to be called to get noreturn behavior purposefully. Further, I think it's also desirable to do this in a unified way. Some questions are:

1. Are the intents of these abort/terminate exactly indentical(Nothing more than should not be called at runtime)?
2. Is _Fake_no_copy_callable_adapter's usage of terminate replaceable with abort?
3. Is it desirable to replace direct usage of abort with a specific utility(like a _MACRO()), to express the intent more clearly?
4. Is "abort" preferrable behavior in these conditions? Are there other candidates for it?
