It looks like that can be triggered by indirect calls:
```
typedef void T(void);
void test3(T f) {
f();
}
```
Since this adds the attribute to definitions and not to call sites, we should
never need that.
This patch is for the case where `CreateGlobalInitOrDestructFunction` ends up
re-using the same function to attach the attributes.
I'll update the description to make it more clear.
