reduce compiler `Assemble` complexity
`compile::Assemble` is already complicated by its nature (as it handles core internals like recursive building logic, etc.) and also handles half of `LldWrapper` tool logic for no good reason since it should be done in the build step directly.
This change moves it there to reduce complexity of `compile::Assemble` logic.

Fix `x build --stage 1 std` when using cg_cranelift as the default backend
Before, cg_cranelift would ICE when trying to lower f16 and f128. The library/ crates had all the infrastructure to omit using them, it just wasn't hooked up to bootstrap.

bootstrap: use specific-purpose ui test path for `test_valid` self-test
I wanted to move some ui tests around in #134418, which broke `test_valid` since it was referencing two non-specific-purpose ui tests. This PR instead adds two dummy tests under `tests/ui/bootstrap/self-test/`, for that purpose specifically.

Promote powerpc64le-unknown-linux-musl to tier 2 with host tools
MCP: https://github.com/rust-lang/compiler-team/issues/803
I'm using crosstool-ng for building a toolchain because GCC 9 from `musl-toolchain.sh` has float ABI issues (?) and can't compile LLVM, and writing a crosstool-ng config for a target feels less hacky than yet another target specific shell script. I also defined a kernel version, since there wasn't one specified before. If a lower version is desired, just let me know. I also tried to match the rust configure args with the loongarch64 musl tier 2 target.
The resulting compiler works fine, built with `DEPLOY=1 ./src/ci/docker/run.sh dist-powerpc64le-linux` and tested on Alpine Linux in a VM and on a bare metal POWER8 machine:

On Neutrino QNX, reduce the need to set archiver via environment variables
This adds support for automatically selecting the correct `ar` tool when compiling for Neutrino QNX.
Once https://github.com/rust-lang/cc-rs/pull/1319 is merged and a new cc version is integrated, all environment variables of the [Neutrino documentation](https://github.com/rust-lang/rust/blob/stable/src/doc/rustc/src/platform-support/nto-qnx.md) can be removed.

We don't need `NonNull::as_ptr` debuginfo
In order to stop pessimizing the use of local variables in core, skip debug info for MIR temporaries in tiny (single-BB) functions.
For functions as simple as this -- `Pin::new`, etc -- nobody every actually wants debuginfo for them in the first place. They're more like intrinsics than real functions, and stepping over them is good.
Revert "bootstrap: print{ln}! -> eprint{ln}! (take 2) #134040"
Unfortunately, #134040 is proving to have caused more output interleaving problems that are tricky to diagnose and fix, and I think we probably should leave these untouched as bootstrap and compiletest has a bunch of interconnecting parts, and the commands and tools that they exercise do not consistently use stderr/stdout either. This causes hard-to-diagnose output interleaving bugs, which unfortunately degrades contributor experience.
This PR reverts two PRs in order to cleanly revert #134040:
1. Revert #134123 which is a fix-forward after #134040.
2. Revert #134040 itself.
I don't regret the initial effort `@clubby789,` and thank you for making the attempts, but I think we need to refrain from touching too many of these at once because some of the interleaving are very non-obvious and we don't have test coverage for.

allow `symbol_intern_string_literal` lint in test modules
Since #133545, `x check compiler --stage 1` no longer works because compiler test modules trigger `symbol_intern_string_literal` lint errors. Bootstrap shouldn't control when to ignore or enable this lint in the compiler tree (using `Kind != Test` was ineffective for obvious reasons).
Also, conditionally adding this rustflag invalidates the build cache between `x test` and other commands.
This PR removes the `Kind` check from bootstrap and handles it directly in the compiler tree in a more natural way.
bootstrap: Forward cargo JSON output to stdout, not stderr

use vendor sources by default on dist tarballs
Tarball sources are distributed with vendor sources along with the `.cargo/config.toml` file configured for vendor sources. This means we can use vendor sources by default unless explicitly disabled with `build.vendor=false` by the user. So, let's do that.
handle `--json-output` properly
Because `rustfmt` doesn't support JSON output, `x test --json-output` doesn't respect the `--json-output` flag during formatting step. This change makes that `x test` skips the formatting step if `--json-output` is specified. In addition, resolves#133855 with the 2nd commit.
Replace black with ruff in `tidy`
`ruff` can both lint and format Python code (in fact, it should be a mostly drop-in replacement for `black` in terms of formatting), so it's not needed to use `black` anymore. This PR removes `black` and replaces it with `ruff`, to get rid of one Python dependency, and also to make Python formatting faster (although that's a small thing).
If we decide to merge this, we'll need to "reformat the world" - `ruff` is not perfectly compatible with `black`, and it also looks like `black` was actually ignoring some files before. I tried it locally (`./x test tidy --extra-checks=py:fmt --bless`) and it also reformatted some code in subtrees (e.g. `clippy` or `rustc_codegen_gcc`) - I'm not sure how to handle that.
skip `setup::Hook` on non-git sources
Running `setup::Hook` (with `x setup`) leads tarball sources to panic and this PR resolves that problem by skipping `Hook` step on non-git sources.
Improve bootstrap job objects
This attempts to fix a few comments on bootstrap job objects.
I also fixed an issue where if duplicating the job object handle into the python process failed, it would close the job object. This would then result in the job object closing all attached processes, which at that point includes the current process. The fix is to simply never close the job object handle at any point after the current process is assigned to it.
This reverts commit 0585134e70, reversing
changes made to 5530869e0f.
The PR unfortunately only converted the `ln!` instances, meaning that
test output was messed up because stdout/stderr output interleaved when
some `println!` instances were converted to `eprintln!` instances, while
some `println!` instances remain unchanged.
Include LLDB and GDB visualizers in MSVC distribution
MSVC distributions currently don't include the lldb or GDB python files. MSVC and LLDB/GDB are not mutually exclusive (and end up being a common case with vscode + codelldb/lldb-dap), so they should probably be included.
the existing visualizers currently only partially work on MSVC due to the differences in how the debug info is generated, but they also only partially work on GNU anyway - both of which are actively being fixed.
