ice: Unexpected type for constructor

This triggers only with parallel compiler it seems 🤔

snippet:

struct T;

struct Tuple(i32);

async fn foo() -> Result<(), ()> {
    Unstable2(())
}

async fn tuple() -> Tuple {
    Tuple(1i32)
}

async fn match_() {
    match tuple() {
        Tuple(_) => {}
    }
}

Ouff this bisects to #117213 cc @oli-obk

That PR just exposed the issue. It was preexisting

I'm not able to reproduce this with 496145b9cc023aef4bb1f16c0964a53d0da36c88. Perhaps it was fixed by
#127311?
