There is no way (within standard C++) to call this function from outside
the translation unit, because there is no way to refer to the _TestEnum
type. Hence there's no need to emit code for it if it's not called within
the translation unit. You can force code to be generated by marking it with
__attribute__((used)), but it will still be given internal linkage.
