add more Cortex-R targets
This expands on PR #53663 to complete the set of Cortex-R targets and builds
rust-std components for them.
r? @alexcrichton
each extra rust-std component (there's 4 of them) takes about 3 minutes to build
on my local machine. In terms of stability (LLVM codegen bugs) these new targets
should be as stable as the Cortex-M ones (e.g. `thumbv7m-none-eabi`).
If the extra build time is too much we can leave the rust-std components out for
now
closes#53663

Restructure hir::map::Node and hir::map::Entry
- Moves `hir::map::Node` to `hir::Node` and removes the `Node*` prefix from its variants.
- Changes `hir::map::Entry` to a struct `hir::map::Entry`.
- Removes the `Node*` prefix from each of `AnnNode`s variants.

document the platform-specific behavior of Command::current_dir
See also https://github.com/rust-lang/rust/issues/37868.
Here's my initial wording:
> Note that if the program path is relative (e.g. `"./script.sh"`), the interaction between that path and `current_dir` varies across platforms. Windows currently ignores `current_dir` when locating the program, but Unix-like systems interpret the program path relative to `current_dir`. These implementation details aren't considered stable, and it's recommended to call `canonicalize` to get an absolute program path instead of using relative paths and `current_dir` together.
I'd like to get feedback on:
- _Should_ we consider those details stable? It might be disruptive to change them, regardless of what I can get away with claiming in docs :)
- Is `canonicalize` an appropriate recommendation? As discussed in #37868 above, there are reasons it's not called automatically in the `Command` implementation.

TODO:
- [x] Make sure the tests pass.
- [x] Make sure there is rustfix-able suggestion. Current plan is to just suggest `_ : Foo`
- [x] Add a rustfix ui test.
EDIT: It seems I already did the last two in #48309
move the Pin API into its own module for centralized documentation
This implements the change proposed by @withoutboats in #49150, as suggested by @RalfJung in the review of #53104,
along with the documentation that was originally in it, that was deemed more appropriate in module-level documentation.
r? @RalfJung
resolve suggestions should use `crate::` when enabled
I couldn't find a way to add a specific assertion for the ui test, so the expected output is living under the `crates-in-path.stderr` ui test.
- is this the right place for the test?
fixes#51212
This commit updates the `unused_extern_crates` lint to make automatic
suggestions about removing `extern crate` annotations in the 2018 edition. This
ended up being a little easier than originally though due to what's likely been
fixed issues in the resolver!
Closes#52829
