James Price 5c61d6d12c msl: Fold &* when converting module-scope vars
This transform was previously converting this code:
```
var<private> v : f32;
fn foo() {
  bar(&v);
}
```

into this:
```
fn foo(vp : ptr<private, f32>) {
  bar(&*vp); // Invalid, since ptr args must be &ident
}
```

Fixed: tint:1086
