Esteban Küber 60b227accc Recognize type Alias = dyn Trait in fn return types 
```
error[E0277]: the size for values of type `(dyn Debug + 'static)` cannot be known at compilation time
  --> $DIR/dyn-trait-type-alias-return-type.rs:4:11
   |
LL | fn f() -> T { loop {} }
   |           ^ doesn't have a size known at compile-time
   |
   = help: the trait `Sized` is not implemented for `(dyn Debug + 'static)`
note: this type alias is unsized
  --> $DIR/dyn-trait-type-alias-return-type.rs:1:1
   |
LL | type T = dyn core::fmt::Debug;
   | ^^^^^^
   = note: the return type of a function must have a statically known size
