bors 41dc3942eb Auto merge of #75608 - estebank:suggest-boxed-match-exprs, r=lcnr,varkor 
More structured suggestions for boxed trait objects instead of impl Trait on non-coerceable tail expressions

When encountering a `match` or `if` as a tail expression where the
different arms do not have the same type *and* the return type of that
`fn` is an `impl Trait`, check whether those arms can implement `Trait`
and if so, suggest using boxed trait objects.

Use structured suggestion for `impl T` to `Box<dyn T>`.
