However I think this is not a regression, because

> struct Foo {
>     union {
>         immutable static struct { double x, y; }

This line is an anonymous struct declaration with 'static' attribute, so
x and y should become immutable static field. Therefore

>         immutable double[2] v;
>     }
>     Foo bar() {
>         return Foo(y, x);
>     }
> }
> void main() {}

In git head, Foo.x and Foo.y are correctly analyzed as static fields, and Foo
has only one instance field v.
