I have a question I'd like to ask about the following case:
```cpp
int v1;
struct S {
static int i __attribute__((alias("v1")));
};
int S::i = 12;
```
Should
```static int i __attribute__((alias("v1")));```
be considered a definition or merely a declaration here?
According to the standard C++ rules, an in-class declaration of a non-inline
static data member is normally not a definition.
However, under the semantics of the alias extension, the alias declaration
itself appears to define the corresponding symbol.
So I'm a little unsure how this declaration should be classified in this case.
