pub use into the top-level crate module does not work

[mzabaluev]

While #4202 has been fixed, a yet simpler case is still reproducible in current incoming.
If I have a crate def.rs with these definitions:

pub use inner::A;

mod inner {
    pub struct A;

    impl A {
        pub fn f() {
        }
    }
}

Then use.rs that uses the crate of def.rs:

extern mod def;

fn main() {
    def::A::f();
}

Compilation of use.rs fails:

use.rs:4:4: 4:13 error: not a module `A`
use.rs:4     def::A::f();
             ^~~~~~~~~

Should be noted that the fix for #4202 applies specifically to static methods on traits. Impls providing static methods on structs may require similar juggling. I'll try to take a look this week if nobody beats me to it.

Pretty sure the fix for this would be a generalization of #4202, but the change is a little more involved because we'll need to track the impls associated with exportable items (struct, trait, maybe enum?).
