Esteban Küber 385eea1d46 Consider methods from traits when suggesting typos
Do not provide a structured suggestion when the arguments don't match.

```
error[E0599]: no method named `test_mut` found for struct `Vec<{integer}>` in the current scope
  --> $DIR/auto-ref-slice-plus-ref.rs:7:7
   |
LL |     a.test_mut();
   |       ^^^^^^^^
   |
   = help: items from traits can only be used if the trait is implemented and in scope
note: `MyIter` defines an item `test_mut`, perhaps you need to implement it
  --> $DIR/auto-ref-slice-plus-ref.rs:14:1
   |
LL | trait MyIter {
   | ^^^^^^^^^^^^
help: there is a method `get_mut` with a similar name, but with different arguments
  --> $SRC_DIR/core/src/slice/mod.rs:LL:COL
```

Consider methods beyond inherent ones when suggesting typos.

```
error[E0599]: no method named `owned` found for reference `&dyn Foo` in the current scope
  --> $DIR/object-pointer-types.rs:11:7
   |
LL |     fn owned(self: Box<Self>);
   |                    --------- the method might not be found because of this arbitrary self type
...
LL |     x.owned();
   |       ^^^^^ help: there is a method with a similar name: `to_owned`
```
