Clearer use of the error message and span labels to communicate
duplicaiton defitions/imports.
New error format:
```
error[E0428]: the name `Foo` is defined twice
--> example.rs:2:1
|
1 | trait Foo { }
| ------------- previous definition of the trait `Foo` here
2 | struct Foo { }
| ^^^^^^^^^^^^^^ `Foo` redefined here
= note: `Foo` must be defined only once in the type namespace of this module
error: aborting due to previous error
