[Rust 2018] pub use some_crate as some_name breaks glob imports

[CryZe]

Let's say lib.rs contains:

pub use some_crate as some_name;

in order to make a crate available as a different name, using a glob import in the same crate (but other file) as such:

use crate::some_name::*;

doesn't actually import anything into scope, while using explicit imports or pub extern crate some_crate as some_name; instead works. This is possibly related to #52140

visited for triage. P-high. Not sure who is going to work on it; @petrochenkov do you think you have space on your plate to look at this?

[petrochenkov]

The reason is probably that resolution for single-segment imports is implemented as a special case in fn finalize_import, it probably should happen in some other function that's called earlier than "finalize".

If someone can investigate this now, please do.
I'll be able to do it in 3-4 weeks.

Visiting during compiler meeting. It appears that @eddyb and @petrochenkov have been discussing this bug over in #52923, going to assign to @eddyb
