This code triggers an ICE:

#![feature(unsafe_destructor)]


trait Bar<'b> {
    fn do_something(&mut self);
}

struct BarImpl<'b>;

impl<'b> Bar<'b> for BarImpl<'b> {
    fn do_something(&mut self) {}
}


struct Foo<B>;

#[unsafe_destructor]
impl<'b, B: Bar<'b>> Drop for Foo<B> {
    fn drop(&mut self) {}
}


fn main() {
    // note: the call to unitialized() is not important, it's just here
    // because the destructor needs to be called for the ICE to trigger
    let x: Foo<BarImpl> = unsafe { std::mem::uninitialized() };
}

Message:

<anon>:1:1: 1:1 error: internal compiler error: Type parameter out of range when substituting in region 'b (root type=None)

note: the compiler hit an unexpected failure path. this is a bug.

feat!: create alias when renaming an import.

![gif](https://github.com/rust-lang/rust-analyzer/assets/57047985/c593d9a8-b8a0-4e13-9e50-a69c7d0d8749)

Closes rust-lang#15858

Implemented:
- [x] - Prevent using `reserved` keywords (e.g self) and `_`.
- [x] - Rename other modules that might be referencing the import.
- [x] - Fix "broken" tests.
- [ ] - Rename **only** "direct" references.
- [ ] - Test more cases.

Future possibilities:
1. Also support `extern crate <name>` syntax.
2. Allow aliasing `self` when it is inside an `UseTreeList`.
~3. If import path already has an alias, "rename" the alias.~
~[4. Create alias even if path is not the last path segment.](rust-lang/rust-analyzer#16489 (comment)
