This is not actually unreachable, so don't use llvm_unreachable for it. Since

the intent seems to be to terminate even in Release builds, just use abort()
directly.

If program flow ever reaches a __builtin_unreachable (which llvm_unreachable is
#define'd to on newer GCCs) then the program is undefined.
