distinct anonymous structs remain distinct despite having similar layout.
This is already ensured by distinguishing based on their placement in the parent
struct, using the function `findAnonymousStructOrUnionIndex`.
The problem is that this function only handles anonymous structs, like
```
class Foo { struct { int a; } }
```
and not untagged structs like
```
class Foo { struct { int a; } var; }
```
Both need to be handled, and this patch fixes that. The test case ensures that this functionality doesn't regress.
Thanks to Manman Ren for review.
