Auto merge of #34682 - CensoredUsername:clobber-docs, r=eddyb
Correct inline assembly clobber formatting.
Fixes the formatting for inline assembly clobbers used in the book.
As this causes llvm to silently ignore the clobber an error is also
added to catch cases in which the wrong formatting was used.
Additionally a test case is added to confirm that this error works.
This fixes #34458
Note: this is only one out of a few possible ways to fix the issue
depending on how the asm! macro formatting is wanted.
Additionally, it'd be nicer to have some kind of test or feedback
from llvm if the clobber constraints are valid, but I do not know
enough about llvm to say if or how this is possible.

rustbuild: Remove the `build` directory
The organization in rustbuild was a little odd at the moment where the `lib.rs`
was quite small but the binary `main.rs` was much larger. Unfortunately as well
there was a `build/` directory with the implementation of the build system, but
this directory was ignored by GitHub on the file-search prompt which was a
little annoying.
This commit reorganizes rustbuild slightly where all the library files (the
build system) is located directly inside of `src/bootstrap` and all the binaries
now live in `src/bootstrap/bin` (they're small). Hopefully this should allow
GitHub to index and allow navigating all the files while maintaining a
relatively similar layout to the other libraries in `src/`.

Fix expansion performance regression
**syntax-[breaking-change] cc #31645**
This fixes #34630 by reverting commit 5bf7970 of PR #33943, which landed in #34424.
By removing the `Rc<_>` wrapping around `Delimited` and `SequenceRepetition` in `TokenTree`, 5bf7970 made cloning `TokenTree`s more expensive. While this had no measurable performance impact on the compiler's crates, it caused an order of magnitude performance regression on some macro-heavy code in the wild. I believe this is due to clones of `TokenTree`s in `macro_parser.rs` and/or `macro_rules.rs`.

Auto merge of #34412 - gnzlbg:document_platform_intrinsics_generate, r=alexcrichton
Add x86 intrinsics for bit manipulation (BMI 1.0, BMI 2.0, and TBM).
This PR adds the LLVM x86 intrinsics for the bit manipulation instruction sets (BMI 1.0, BMI 2.0, and TBM).
The objective of this pull-request is to allow building a library that implements all the algorithms offered by those instruction sets, using compiler intrinsics for the targets that support them (by means of `target_feature`).
The target features added are:
- `bmi`: Bit Manipulation Instruction Set 1.0, available in Intel >= Haswell and AMD's >= Jaguar/Piledriver,
- `bmi2`: Bit Manipulation Instruction Set 2.0, available in Intel >= Haswell and AMD's >= Excavator,
- `tbm`: Trailing Bit Manipulation, available only in AMD's Piledriver (won't be available in newer CPUs).
The intrinsics added are:
- BMI 1.0:
- `bextr`: Bit field extract (with register).
- BMI 2.0:
- `bzhi`: Zero high bits starting with specified bit position.
- `pdep`: Parallel bits deposit.
- `pext`: Parallel bits extract.
- TBM:
- `bextri`: Bit field extract (with immediate).
Move LLVM cleanup so modules are accessible during `after_llvm` phase
Fix for #34432. Also added a new phase controller `after_compilation_done` that gets called at the very end (i.e. after linking) at the suggestion of @nrc. The added test will segfault if the modules get deallocated too early, so it ensures the LLVM is not prematurely cleaned up.

prefer `if let` to match with `None => {}` arm in some places
This is a spiritual succesor to #34268 / 8531d581, in which we replaced a
number of matches of None to the unit value with `if let` conditionals
where it was judged that this made for clearer/simpler code (as would be
recommended by Manishearth/rust-clippy's `single_match` lint). The same
rationale applies to matches of None to the empty block.

The only things that separate these entry points from `after_hir_lowering` are dep-info generation and HIR map construction, neither of which is computationally intensive or has the potential to error.

It seems python broke compatability between 2.7.9 and 2.7.12 as on the former a WindowsError was raised while on the latter a subprocess.CalledProcessError was raised while testing for the existence of uname.
As a WindowsError being thrown obviously indicates we're running on windows, this should probably be accepted too.

Disallow constants and statics from having unsized types.
This is a `[breaking-change]` which fixes #34390 by banning unsized `const` and `static`, e.g.:
```rust
const A: [i32] = *(&[0, 1, 2] as &[i32]);
static B: str = *"foo";
```
This was not intentionally allowed, and other than for `static` since some versions ago, it ICE'd.
If you've been taking advantage of this with `static`, you should be able to just use references instead.
