`concat_idents!` was deprecated in [1] and will be removed in the near
future. rust-analyzer's support is independent of rustc's, so drop RA
support now to make syncing easier.

Implement `advance_by` via `try_fold` for `Sized` iterators
When `try_fold` is overriden, it is usually easier for compilers to optimize.
Example difference: https://iter.godbolt.org/z/z8cEfnKro
Use the fn_span when emitting function calls for better debug info.
This especially improves the developer experience for long chains of function calls that span multiple lines, which is common with builder patterns, chains of iterator/future combinators, etc.

Update IDEs to use rustfmt 2024, fix Zed settings
Update IDEs to use rustfmt 2024, fix Zed settings
- Update IDE `rust-analyzer` settings to use 2024 rather than 2021.
- Fix Zed settings by removing `${workspaceFolder}/` from paths.
Fast path for processing some obligations in the new solver
Fast path applies to:
- Dyn compatibility predicates
- Region and type outlives predicates
- Trivially sized predicates
Emit a warning if the doctest `main` function will not be run
Fixes#140310.
I think we could try to go much further like adding a "link" (ie UI annotations) on the `main` function in the doctest. However that will require some more computation, not sure if it's worth it or not. Can still be done in a follow-up if we want it.
For now, this PR does two things:
1. Pass the `DiagCtxt` to the doctest parser to emit the warning.
2. Correctly generate the `Span` to where the doctest is starting (I hope the way I did it isn't too bad either...).

Match on lang item kind instead of using an if/else chain
Similar to how the new solver does this. Just noticed while I was adding a new entry to the chain 😆
[win][ci] Update LLVM toolchain used to build LLVM to 20
While trying to get the aarch64-msvc build working correctly (#140136), I needed to update the version of LLVM used to build LLVM in Windows CI runners to 20 (as this has improved support for Arm64 and Arm64EC on Windows).
This catches Windows up to Linux which was updated to 20 by #137189

update llvm-tools logic for `dist` and `install` steps
First commit aligns `build_steps::compile` and `build_steps::dist` logics for copying llvm-tools, and the second commit adds the correct `should_run` condition for `LlvmTools` step as the previous one was clearly incorrect.
Fixes#140913
