miri-script: use --remap-path-prefix to print errors relative to the right root
Inspired by https://github.com/rust-lang/rust-clippy/pull/13232, this makes it so that when cargo-miri fails to build, `./miri check` will print errors with paths like `cargo-miri/src/setup.rs`. That means we can get rid of the miri-symlink-hacks and instead tell RA to just always invoke the `./miri clippy` script just once, in the root.
This means that we can no longer share a target dir between cargo-miri and miri as the RUSTFLAGS are different to crates that are shared in the dependency tree need to be built twice with two different flags. `miri-script` hence now has to set the MIRI environment variable to tell the `cargo miri setup` invocation where to find Miri.
I also made it so that errors in miri-script itself are properly shown in RA, for which the `./miri` shell wrapper needs to set the right flags.
Apply "polymorphization at home" to RawVec
The idea here is to move all the logic in RawVec into functions with explicit size and alignment parameters. This should eliminate all the fussing about how tweaking RawVec code produces large swings in compile times.
This uncovered https://github.com/rust-lang/rust-clippy/issues/12979, so I've modified the relevant test in a way that tries to preserve the spirit of the test without tripping the ICE.
Link `std` statically in `rustc_driver`
This makes `rustc_driver` statically link to `std`. This is done by not passing `-C prefer-dynamic` when building `rustc_driver`. However building `rustc-main` won't work currently as it tries to dynamically link to both `rustc_driver` and `std` resulting in a crate graph with `std` duplicated. To fix that new command line option `-Z prefer_deps_of_dynamic` is added which prevents linking to a dylib if there's a static variant of it already statically linked into another dylib dependency.
The main motivation for this change is to enable `#[global_allocator]` to be used in `rustc_driver` allowing overriding the allocator used in rustc on all platforms.
---
Instead of adding `-Z prefer_deps_of_dynamic`, this PR is changed to crate opt-in to the linking change via the `rustc_private` feature instead, as that would be typically needed to link to `rustc_driver` anyway.

Promote aarch64-apple-darwin to Tier 1
This promotes aarch64-apple-darwin to Tier 1 status as per rust-lang/rfcs#3671 and tracking issue #73908. Not sure what else is necessary for this to impement the aforementioned RFC, however I figured I'd try. I did read in previous issues and PRs that the necessary infrastructure was already in place for the aarch64-apple-darwin target, and the RFC mentions the same. So this should be all thats necessary in order for the target to be promoted.
This is a recreation of my previous PR because I accidentally did an incorrect git rebase which caused unnecessary changes to various commit SHAs. So this PR is a recreation of my previous PR without said stumble. My bad.
[rustdoc] Stop showing impl items for negative impls
Fixes https://github.com/rust-lang/rust/issues/128799.
As discussed with `@fmease,` they have a broader patch in progress, so this (small) PR will at least allow for them to have a regression test. :)

Enable zstd for debug compression.
Set LLVM_ENABLE_ZSTD alongside LLVM_ENABLE_ZLIB so that --compress-debug-sections=zstd is an option.

Subtree sync for rustc_codegen_cranelift
The main highlight this time is support for raw-dylib on Windows thanks to `@dpaoliello.` Compiling the ring crate for arm64 macOS has been fixed too.

Disable verbose bootstrap command failure logging by default
One of my recent bootstrap command refactoring PRs enabled verbose logging of command failures by default. While this is great for debugging bootstrap, in many situations it's just too verbose and prevents the user from seeing the actual printed stdout/stderr, which usually contains much more useful information.
This PR reverts that logic, and only prints a detailed error when `-v` is passed to bootstrap.

add `builder-config` into tarball sources
This will be useful for certain scenarios where developers want to know how the tarball sources were generated. We also want this to check for CI rustc incompatible options on bootstrap.

VxWorks code refactored
1. Extern TaskNameSet as minimum supported version of os is VxWorks 7 which would have taskNameSet
2. Vx_TASK_NAME_LEN is 31 on VxWorks7, defined variable res.
3. Add unsafe blocks on Non::Zero usage in available_parallelism()
4. Update vxworks docs.

Set LLVM_ENABLE_ZSTD alongside LLVM_ENABLE_ZLIB so that --compress-debug-sections=zstd is an option.
Use static linking to avoid a new runtime dependency. Add an llvm.libzstd bootstrap option for LLVM
with zstd. Set it off by default except for the dist builder. Handle llvm-config --system-libs output
that contains static libraries.
Miscellaneous improvements to struct tail normalization
1. Make checks for foreign tails more accurate by normalizing the struct tail. I didn't write a test for this one.
2. Normalize when computing struct tail for `offset_of` for slice/str. This fixes the new solver only.
3. Normalizing when computing tails for disaligned reference check. This fixes both solvers.
