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
```

include both named an anonymous modules, and fix #31644
|
|
Change build_reduced_graph.rs so the fields def and module of NsDef are never both Some unless the NsDef represents a duplicate definition (see issue 26421).

This will break code that looks like:
struct Foo {
...
}
mod Foo {
...
}
Change this code to:
struct Foo {
...
}
impl Foo {
...
}
Or rename the module.
Closes #15205.
