There is also some work here to make resolve a bit more stable - it no longer overwrites a specific import with a glob import.
[breaking-change]
Import shadowing of single/list imports by globs is now forbidden. An interesting case is where a glob import imports a re-export (`pub use`) of a single import. This still counts as a single import for the purposes of shadowing .You can usually fix any bustage by re-ordering such imports. A single import may still shadow (override) a glob import or the prelude.
* Both enums already derived `Copy`, but storing them in any
struct/container would prevent implementing `Clone` for said
struct/container even though they should be clonable.
* Also add PartialEq and Eq for good measure.
It's quite possible that small programs don't use all of jemalloc, and building
with -ffunction-sections and -fdata-sections allows the linker (via
--gc-sections) to strip out all unused code at link time. This decreases the
size of a "hello world" executable for me from 716K to 482K with no measurable
impact on link time. After this patch jemalloc is still the largest portion of
our hello world executables, but this helps cut down on the size at least
somewhat!
#20075 introduced a bug where unmarked code fences weren't considered as doctests. This PR fixes the logic.

This passed `check-stage1-rustdoc`, and I manually checked that:
``` rust
//! ```
//! println!("Hello")
//! ```
//!
//! ``` rust
//! println!("Hello")
//! ```
//!
//! ``` sh
//! println!("Hello")
//! ```
//!
//! ``` ignore
//! println!("Hello")
//! ```
```
Generated:
``` rust
running 3 tests
test _2 ... ignored
test _0 ... ok
test _1 ... ok
```
I'd love to add that as a test, but I have no idea how to do that with our testing infrastructure. If anyone knows how, do let me know!

@seanmonstar feedback?
Add support for all variants of ast::WherePredicate in clean/mod.rs. Fixes#20048, but will need modification when EqualityPredicates are fully implemented in #20041.
... really this time `:)`
I went for the simpler fix after all since it turned out to become a bit too complicated to extract the current iteration value from its containing `Option` with the different memory layouts it can have. It's also what we already do for match bindings.
I also extended the new test case to include the "simple identifier" case.
Fixes#20127, fixes#19732
