Add `normalize()` in run-make `Diff` type
I need it to do the same as:
```
//@ normalize-stdout-test "finished in \d+\.\d+s" -> "finished in $$TIME"
```
in doctests.
I need it in particular for the https://github.com/rust-lang/rust/pull/123974 PR (which contains this commit until this PR current PR is merged).

Write `git-commit-{sha,info}` for Cargo in source tarballs
Right now Cargo doesn't populate the commit hash or date in its version output when it's built from the plain source tarball. That's because we don't include the git information for it, and Cargo's build script doesn't pick it up.
This PR *partially* solves the problem by storing the git information for Cargo in `src/tools/cargo` in the plain source tarball. We store separate information because even when built in CI Cargo uses its own git information rather than Rust's.
This PR will also require a change in the Cargo repository to consume this information (https://github.com/rust-lang/cargo/pull/13832), but it doesn't have to be blocked on the Cargo PR being merged.
Port repr128-dwarf run-make test to rmake
This PR ports the repr128-dwarf run-make test to rmake, using the `gimli` crate instead of the `llvm-dwarfdump` command.
Note that this PR changes `rmake.rs` files to be compiled with the 2021 edition (previously no edition was passed to `rustc`, meaning they were compiled with the 2015 edition). This means that `panic!("{variable}")` will now work as expected in `rmake.rs` files (there's already a usage in the [wasm-symbols-not-exported test](aca749eefc/tests/run-make/wasm-symbols-not-exported/rmake.rs (L34)) that this will fix).

Add StaticForeignItem and use it on ForeignItemKind
This is in preparation for unsafe extern blocks that adds a safe variant for functions inside extern blocks.

coverage: Replace boolean options with a `CoverageLevel` enum
After #123409, and some discussion at https://github.com/rust-lang/rust/issues/79649#issuecomment-2042093553 and #124120, it became clear to me that we should have a unified concept of “coverage level”, instead of having several separate boolean flags that aren't actually independent.
This PR therefore introduces a `CoverageLevel` enum, to replace the existing boolean flags for `branch` and `mcdc`.
The `no-branch` value (for `-Zcoverage-options`) has been renamed to `block`, instructing the compiler to only instrument for block coverage, with no branch coverage or MD/DC instrumentation.

Remove direct dependencies on lazy_static, once_cell and byteorder
The relevant functionality of all three crates is now available and stable in the standard library, i.e. `std::sync::OnceLock` and `{integer}::to_le_bytes`. I think waiting for `LazyLock` (#109736) would give marginally more concise code, but not by much.
CI: remove `master` job
It only had one job (pun intended), to publish the toolstate. We could probably do that at the end of `auto` builds instead, which is what is done in this PR.

Port `print-cfg` run-make test to Rust-based rmake.rs
This PR port the `print-cfg` run-make test to Rust-based rmake.rs tests.
The actual test is now split in two:
- the first part for the `--print=cfg` part
- and the second part for the `=PATH` part of `--print`
Part of #121876.

drop deprecated value `if-available` for `download-ci-llvm` option
It's been 5 months since we deprecated this. It should be fine to drop its support now.
Bootstrap: Check validity of `--target` and `--host` triples before starting a build
Resolves#122128
As described in the issue, validating the `target` and `host` triples would save a lot of time before actually starting a build. This would also check for custom targets by looking for a valid JSON spec if the specified target does not exist in the [supported](42825768b1/compiler/rustc_target/src/spec/mod.rs (L1401-L1689)) list of targets.
bootstrap: Document `struct Builder` and its fields
I'm exploring the code of bootstrap and had a bit of a hard time understanding exactly what `Builder` is for at first. I decided to help document it and its field to help future explorers.
bootstrap: Describe build_steps modules
One of my preferred ways to understand source code is to start with its API. This implies the code is documented reasonably accurately, even if it is a private API. The description of one of these modules had not been updated since 2015 and so was both terse and confusing, so I rewrote it. Then I noticed many others went unremarked, so I offered some remarks.
`x vendor`
This PR implements `x vendor` on bootstrap; enabling dependency vendoring without the need for developers to have `cargo` installed on their system (previously, we suggested running `cargo vendor ...` but now we can accomplish the same task with `x vendor`).
In addition, fixes#112391 problem.

bootstrap: Change `global(true)` to `global = true` for flags for consistency
All other arg properties use the `prop = value` style, which makes it slightly annoying to use the `prop(value)` only style for `global`. Change to `prop = value` also for `global` for consistency.
Remove lazycell and once_cell from compiletest dependencies
Use the standard library `OnceLock` instead of third-party equivalents. A macro is used for the regexes to make their initialization less unwieldy.
miri core/alloc tests: do not test a 2nd target
check-aux seems to be one of the slowest runners since we started running standard library tests in Miri on it. So maybe it'd be better to reduce test coverage a bit by not doing cross-target testing of core and alloc? I don't recall finding target-specific issues in these libraries ever (and we still have the extra test coverage via our [out-of-tree nightly tests](https://github.com/rust-lang/miri-test-libstd)). This gives us more buffer to deal with the fact that the number of tests we run will only grow over time.

ast: Generalize item kind visiting
And avoid duplicating logic for visiting `Item`s with different kinds (regular, associated, foreign).
The diff is better viewed with whitespace ignored.
