This helps downstream forks of the compiler like Ferrocene to have their
own annotations for their own files, without having the upstream
licensing be applied. For Ferrocene specifically we keep custom code in
a top-level ferrocene/ directory, and we don't want the dep5 file to
apply to it.
Add auto notification for changes to stable mir
Adds a new entry to the triagebot configuration file to notify subscribers about changes to the stable MIR. I added myself and `@oli-obk` for now.

Consider target_family as pal
Currently, tidy does not consider code in target_family as platform-specific. This is erroneous and should be fixed.

Fix invalid inlining of reexport of reexport of private item
Fixes https://github.com/rust-lang/rust/issues/108679.
The problem is that a reexport is always resolving to the end type, so if the end type is private, the reexport inlines. Except that if you reexport a public reexport (which reexports the private item), then it should not be inlined again.

feat/refactor: improve errors in case of ident with number at start
Improve parser code when we parse a integer (or float) literal but expect an identifier. We emit an error message saying that identifiers can't begin with numbers. This PR just improves that code and expands it to all identifiers. Note that I haven't implemented error recovery (this didn't exist before anyway), I might do that in a follow up PR.

Do not consider `&mut *x` as mutating `x` in `CopyProp`
This PR removes an unfortunate overly cautious case from the current implementation.

Set `LIBC_CHECK_CFG=1` when building Rust code in bootstrap
Downstream forks of the Rust compiler might want to use a custom `libc` to add support for targets that are not yet available upstream. Adding a patch to replace `libc` with a custom one would cause compilation errors though, because Cargo would interpret the custom `libc` as part of the workspace, and apply the check-cfg lints on it.
Since https://github.com/rust-lang/libc/pull/3037, the `libc` build script emits check-cfg flags only when the `LIBC_CHECK_CFG` environment variable is set, so this PR allows the use of custom `libc`s.
