Move placeholder handling to a proper preprocessing step
This commit breaks out the logic of placheolder rewriting into its own preprocessing step. It's one of the more boring
parts of #130227.
The only functional change from this is that the preprocessing step (where extra `r: 'static` constraints are added) is performed upstream of Polonius legacy, finally affecting Polonius. That is mostly a by-product, though.
This should be reviewable by anyone in the compiler team, so

x86 (32/64): go back to passing SIMD vectors by-ptr
Fixes https://github.com/rust-lang/rust/issues/139029 by partially reverting https://github.com/rust-lang/rust/pull/135408 and going back to passing SIMD vectors by-ptr on x86. Sadly, by-val confuses the LLVM inliner so much that it's not worth it...
Also fixes https://github.com/rust-lang/rust/issues/141848 by no longer actually using vector registers with the "Rust" ABI.

Don't refer to 'local binding' in extern macro.
When it comes from a macro expansion, the user has no clue what 'local binding' the compiler is talking about, if they don't know the expansion of the macro. Better to just say 'temporary value'.
Don't refer to 'this tail expression' in expansion.
The user has no clue what the compiler is talking about when it says "this tail expression". It is an implementation detail of the macro that it uses a block with tail expression.
Change `tag_field` to `FieldIdx` in `Variants::Multiple`
It was already available as a generic parameter anyway, and it's not like we'll ever put a tag in the 5-billionth field.
This is a first part of pulling smaller pieces out of rust-lang/rust#138759, so

Ensure query keys are printed with reduced queries
Using `-Z query-dep-graph` and debug assertions leads to an ICE that was originally discovered in rust-lang/rust#141700:
> This isn't an incremental bug per se, but instead a bug that has to do with debug printing query keys when debug assertions and `-Z query-dep-graph` is enabled. We end up printing a const (b/c we're using generic const args here) whose debug printing for -Z query-dep-graph requires invoking the same query cyclically 😃
>
> I've pushed a commit which should fix this.
This isn't related to the standard library changes, but instead b/c it seems to be the first usage of `feature(adt_const_params)` in the standard library that ends up being triggered in incremental tests.

Run wfcheck in one big loop instead of per module
Maybe we can merge this big loop in the future with the `par_hir_body_owners` call below and run typeck only on items that didn't fail wfcheck. For now let's just see if perf likes it, as it by itself should be beneficial to parallel rustc
Use non-2015 edition paths in tests that do not test for their resolution

Fix for async drop inside async gen fn
Return value (for yield) is corrected for async drop inside async gen function.
In CFG, when internal async drop future is polled and returned `Poll<()>::Pending`, then async gen resume function returns `Poll<(OptRet)>::Pending`.

bootstrap: don't symlink source dir into stage0 sysroot
In StdLink::run we subsequently recursively copy the initial sysroot lib directory into the stage0-sysroot lib directory. If the initial sysroot is a toolchain that includes the `rust-src` component (in lib/rustlib/src/rust), if we add this symlink, that recursive copy will overwrite the repo sources with the toolchain's sources.

index: add method for checking range on DenseBitSet
Micro-optimisation that Miri benefits from with the new isolated allocator for native-libs mode. Also possibly just a useful method to have on `DenseBitSet`
make `OsString::new` and `PathBuf::new` unstably const
Since #129041, `String::into_bytes` is `const`, which allows making `OsString::new` and `PathBuf::new` unstably const now.
Not sure what the exact process for this is; does it need an ACP?
Improve the documentation of `Display` and `FromStr`, and their interactions
In particular:
- `Display` is not necessarily lossless
- The output of `Display` might not be parseable by `FromStr`, and might
not produce the same value if it is.
- Calling `.parse()` on the output of `Display` is usually a mistake
unless a type's documented output and input formats match.
- The input formats accepted by `FromStr` depend on the type.
This documentation adds no API surface area and makes no guarantees about stability. To the best of my knowledge, everything it says is already established to be true. As such, I don't think it needs an FCP.
Rework `collect_and_apply` to not rely on size hint for optimization
I saw that we have quite a few `collect_and_apply` calls for N=3-7 (N=7 corresponding to cumulative 99% of nalgebra's calls). Didn't perf locally, but also this is super low-pri, so let's see what rust-timer says.
In StdLink::run we subsequently recursively copy the initial sysroot
lib directory into the stage0-sysroot lib directory. If the initial
sysroot is a toolchain that includes the `rust-src` component (in
lib/rustlib/src/rust), if we add this symlink, that recursive copy
will overwrite the repo sources with the toolchain's sources.
