It's better than "array prvalue" but if you're coming from a C background,
that's not going to look like a temporary array to you, either.
What kind of diagnostic would we get for:
```
#define X ({(int[10]){};})
void func() {
(void)(X + 0);
}
```
IIRC there's no rvalue conversion on the statement expression result so I think
that ends up being a prvalue of array type (not a decayed pointer) plus an
integer, so the type information would actually be helpful.
