Referencing fn pointers with associated types of references ICEs

[sgrif]

Example reproduction script:

use std::ops::Deref;

fn main() {
    let x: fn(&i32) -> <&i32 as Deref>::Target = unimplemented!();
}

Looks like this is fixed by #38375 . @petrochenkov ?

[petrochenkov]

No, this is some other older issue, it happens on stable already.

Oh. Thanks for the explain @petrochenkov 😄

This no longer ICEs. E-needstest.
