Preparation for a subsequent change that replaces
rustc_target::config::Config with its wrapped Target.
On its own, this commit breaks the build. I don't like making
build-breaking commits, but in this instance I believe that it
makes review easier, as the "real" changes of this PR can be
seen much more easily.

Rename target_pointer_width to pointer_width because it is already
member of the Target struct.
The compiler supports only three valid values for target_pointer_width:
16, 32, 64. Thus it can safely be turned into an int.
This means less allocations and clones as well as easier handling of the type.
Also change target_pointer_width to pointer_width.
Preparation for a subsequent type change of
target_pointer_width to an integer together with a rename
to pointer_width.

Detect configuration for LLVM during setup
This is a first draft to address #77579, setting `download-ci-llvm` to true on Linux, but I could also implement the `if-available` setting mentioned in the issue.
On other platforms I was thinking about using [the which crate](https://crates.io/crates/which), if adding a dependency on it is considered okay of course, to detect the presence of `llvm-config` in the path, and use it if found. Still a work in progress of course.

I have split this up into tiny comments because I find it clearer this way. Feel free to squash it.
Remove unused code
Rustc has a builtin lint for detecting unused code inside a crate, but when an item is marked `pub`, the code, even if unused inside the entire workspace, is never marked as such. Therefore, I've built [warnalyzer](https://github.com/est31/warnalyzer) to detect unused items in a cross-crate setting.
Closes https://github.com/est31/warnalyzer/issues/2
We need a fresh input buffer each time, or we reuse the previous
data (since `read_line` appends).

Put all()'s otuput in the order we want to print things in, and add a
comment about why they are in this order. Provide purpose() and
all_for_help(). Use these things everywhere.
Move all the abbrev character ("a", "b", etc.) processing into
interactive_path.
No functional change.

bootstrap: only use compiler-builtins-c if they exist
The assignment of `features` above was added in rust-lang#60981, but
never used. Presumably the intent was to replace the string literal here
with it.
While I'm in the area, `compiler_builtins_c_feature` doesn't need to be
a `String`.
I'm not entirely sure of a great way to locally test this -- `./x.py test`
passed on my machine, but 🤷♂️.

Switch rustdoc from `clean::Stability` to `rustc_attr::Stability`
This gives greater type safety and is less work to maintain on the rustdoc end. It also makes rustdoc more consistent with rustc.
Noticed this while working on https://github.com/rust-lang/rust/issues/76998.
- Remove `clean::Stability` in favor of `rustc_attr::Stability`
- Remove `impl Clean for Stability`; it's no longer necessary

Moved the main `impl` for FnCtxt to its own file.
Resolves#77085 without breaking the API of the `FnCtxt` struct.
This is a solution to the file length being over 3000 (see issue #60302).
The other solution to the file length is
1. to change the API of this struct by
2. encapulating certain fields of the struct into other structs.
Codegen backend interface refactor
This moves several things away from the codegen backend to rustc_interface. There are a few behavioral changes where previously the incremental cache (incorrectly) wouldn't get finalized, but now it does. See the individual commit messages.
BTreeMap: fix gdb provider on BTreeMap with ZST keys or values
Avoid error when gdb is asked to inspect a BTreeMap or BTreeSet with a zero-sized type as key or value. And clean up.
