ICE on Struct type aliases

[alexvitkov]

Aim

This code panics with an internal compiler error:

struct Foo {}
type StillFoo = Foo;

fn main() {
    let foo: StillFoo = Foo {};
}

It's caused by the fact that we resolve type aliases before structs -- this example can be fixed by changing the resolution order (calling resolve_type_aliases before resolve_structs), however we can have both structs referencing typedefs and typedefs referencing structs, for which there's no trivial fix:

struct Foo {}
type StillFoo = Foo;

struct Bar {
    foo: StillFoo,
}

fn main() {
    let bar = Bar { foo: Foo{} };
}

Expected Behavior

The examples above work
