#10353 was about the ICE, but now that that has been patched up, we should add this feature.

auto merge of #15831 : rpjohnst/rust/generic-foreign-fns, r=alexcrichton

This allows for things like this:

    extern "C" fn callback<T>(t: T) { /* ... */ }
    extern "C" {
        fn take_callback(c: extern fn(i32));
    }

and later:

    take_callback(callback::<i32>);

Closes #12502.

`assigning_clones` should respect MSRV

Fixes: rust-lang#12502

This PR fixes the `assigning_clones` lint suggesting to use `clone_from` or `clone_into` on incompatible MSRVs.

`assigning_clones` will suggest using either `clone_from` or `clone_into`, both of which were stabilized in 1.63. If the current MSRV is below 1.63, the lint should not trigger.

changelog: [`assigning_clones`]: don't lint when the MSRV is below 1.63.
