Upgrade dependencies in run-make-support
The main purpose of this is to upgrade `object` and `gimli`, which will allow us to drop outdated versions once backtrace also updates. The only semver breakage in `object`'s is in `elf::R_RISCV_GNU_*` and `pe::IMAGE_WEAK_EXTERN_*` constants, as well as Mach-O dyld, which don't appear to be used here. `gimli` is similar, there is only minor breakage related to dyld.
These version upgrades were also done in the library.
`bstr`, `similar`, and `regex` are also upgraded to the latest minor version here to match what the lockfile already uses. The `regex` comment about `memchr` version hasn't been relevant to this lockfile since e95d15a11519 ("Pin memchr to 2.5.0 in the library rather than rustc_ast") and is no longer relevant in the library lockfile either.

mbe: Add tests and restructure metavariable expressions
Add tests that show better diagnostics, and factor `concat` handling to a separate function. Each commit message has further details.
This performs the nonfunctional perparation for further changes such as https://github.com/rust-lang/rust/pull/142950 and https://github.com/rust-lang/rust/pull/142975 .

Introduce `ByteSymbol`
It's like `Symbol` but for byte strings. The interner is now used for both `Symbol` and `ByteSymbol`. E.g. if you intern `"dog"` and `b"dog"` you'll get a `Symbol` and a `ByteSymbol` with the same index and the characters will only be stored once.
The motivation for this is to eliminate the `Arc`s in `ast::LitKind`, to make `ast::LitKind` impl `Copy`, and to avoid the need to arena-allocate `ast::LitKind` in HIR. The latter change reduces peak memory by a non-trivial amount on literal-heavy benchmarks such as `deep-vector` and `tuple-stress`.
`Encoder`, `Decoder`, `SpanEncoder`, and `SpanDecoder` all get some changes so that they can handle normal strings and byte strings.

[COMPILETEST-UNTANGLE 1/N] Move some some early config checks to the lib and move the compiletest binary
This is part of a patch series to untangle `compiletest` to hopefully nudge it towards being more maintainable.
This PR:
- Moves some early config checks (some warnings) to the compiletest library.
- Moves `src/main.rs` to `src/bin/main.rs` to make the separation (as in, compiletest's library component vs the tool binary component) more obvious.

Make combining LLD with external LLVM config a hard error
Younger me made this only a warning in https://github.com/rust-lang/rust/pull/139853, because our post-dist tests were relying on this. But that was not a good idea, because there are a bunch of places in bootstrap that outright try to build LLD/copy LLD to sysroot when `lld_enabled` is true (rightfully so), which is causing issues (https://github.com/rust-lang/rust/issues/143076). Instead of piling more hacks, I'd like to just disallow this, and if we need to use a hack, do it only for our CI.
If this breaks the CI post-dist tests, I'll either add some special environment variable for it, or, as an alternative, make the error back into a warning, but also disable `lld_enabled` when this situation happens.

fix typos and improve clarity in documentation
```
Description:
This pull request corrects minor typos and improves wording for clarity across several documentation files, including:
- Correcting instrinsics → intrinsics
- Correcting preferrably → preferably
- Correcting Orginally → Originally
- Correcting resiliant → resilient

Miri: handling of SNaN inputs in `f*::pow` operations
fixes [miri/#4286](https://github.com/rust-lang/miri/issues/4286) and related to rust-lang/rust#138062 and [miri/#4208](https://github.com/rust-lang/miri/issues/4208#issue-2879058184).
For the following cases of the powf or powi operations, Miri returns either `1.0` or an arbitrary `NaN`:
- `powf(SNaN, 0.0)`
- `powf(1.0, SNaN)`
- `powi(SNaN, 0)`
Also added a macro in `miri/tests/pass/float.rs` which conveniently checks if both are indeed returned from such an operation.
Made these changes in the rust repo so I could test against stdlib, since these were impacted some time ago and were fixed in rust-lang/rust#138062. Tested with:
```fish
env MIRIFLAGS=-Zmiri-many-seeds ./x miri --no-fail-fast std core coretests -- f32 f64
```
This was successful. This does take a while, so I recommend using `--no-doc` and separate use of `f32` or `f64`
The pr is somewhat split up into 3 main commits, which implement the cases described above. The first commit also introduces the macro, and the last commit is just a global refactor of some things.

It's like `Symbol` but for byte strings. The interner is now used for
both `Symbol` and `ByteSymbol`. E.g. if you intern `"dog"` and `b"dog"`
you'll get a `Symbol` and a `ByteSymbol` with the same index and the

The motivation for this is to eliminate the `Arc`s in `ast::LitKind`, to

non-trivial amount on literal-heavy benchmarks such as `deep-vector` and
`tuple-stress`.
`Encoder`, `Decoder`, `SpanEncoder`, and `SpanDecoder` all get some
changes so that they can handle normal strings and byte strings.
This change does slow down compilation of programs that use
`include_bytes!` on large files, because the contents of those files are
now interned (hashed). This makes `include_bytes!` more similar to
`include_str!`, though `include_bytes!` contents still aren't escaped,
and hashing is still much cheaper than escaping.

To make it obvious `compiletest`-the-tool has two components:
1. The core compiletest library, and
2. The tool binary, which will be executed by bootstrap.

It's not necessary anymore due to Rust 2024 lifetime capture rules.

Add shims for `gettid`-esque functions
|
|
Various platforms provide a function to return the current OS thread ID,
but they all use a slightly different name. Add shims for these
functions for Apple, FreeBSD, and Windows, with tests to account for
those and a few more platforms that are not yet supported by Miri. The
syscall and extern symbol is included as well on Linux.
These should be useful in general but will also help support printing
the OS thread ID in panic messages [1].

Add SIMD funnel shift and round-to-even intrinsics
This PR adds 3 new SIMD intrinsics
- `simd_funnel_shl` - funnel shift left
- `simd_funnel_shr` - funnel shift right
- `simd_round_ties_even` (vector version of `round_ties_even_fN`)
TODO (future PR): implement `simd_fsh{l,r}` in miri, cg_gcc and cg_clif (it is surprisingly hard to implement without branches, the common tricks that rotate uses doesn't work because we have 2 elements now. e.g, the `-n&31` trick used by cg_gcc to implement rotate doesn't work with this because then `fshl(a, b, 0)` will be `a | b`)
