Distribute rustc_codegen_cranelift for Windows
With support for raw-dylib recently added to cg_clif, and inline assembly support working on Windows for quite a while now, all blockers for distributing cg_clif on Windows that I mentioned in https://github.com/rust-lang/rust/pull/81746#issuecomment-1774099637 are fixed now.
When linking macOS targets with cc, pass the `-mmacosx-version-min=.`
option to specify the desired deployment target. Also, no longer pass
`-m32`/`-m64`, these are redundant since we already pass `-arch`.
When linking with cc on other Apple targets, always pass `-target`.
(We assume for these targets that cc => clang).
The minimum that `rustc` encoded did not match the version in Clang, and
that meant that that when linking, we ended up bumping the version.
Specifically, this sets the correct deployment target of the following
simulator and Mac Catalyst targets:
- `aarch64-apple-ios-sim` from 10.0 to 14.0
- `aarch64-apple-tvos-sim` from 10.0 to 14.0
- `aarch64-apple-watchos-sim` from 5.0 to 7.0
- `aarch64-apple-ios-macabi` from 13.1 to 14.0
I have chosen to not document the simulator target versions in the
platform support docs, as it is fundamentally uninteresting; the normal
targets (e.g. `aarch64-apple-ios`, `aarch64-apple-tvos`) still have the
same deployment target as before, and that's what developers should
actually target.
in this commit, `naked_asm!` is an alias for `asm!` with one difference: `options(noreturn)` is always enabled by `naked_asm!`. That makes it future-compatible for when `naked_asm!` starts disallowing `options(noreturn)` later.
const: make ptr.is_null() stop execution on ambiguity
This seems better than saying `false` -- saying `false` is in fact actively unsound if `NonNull` then uses this to permit putting this pointer inside of it, but at runtime it turns out to be null.

remove 'const' from 'Option::iter'
This is kind of pointless to be a `const fn` since you can't do anything with the iterator. It is also the only `const fn iter*` in the entire standard library. It probably got constified when `~const` traits got added everywhere, and then was forgotten to be de-constified when that was undone.
The rest of the const_option feature seems like it can reasonably be stabilized, but this one IMO should not be stabilized, and it's not worth creating a new tracking issue.

run-make-support: Add llvm-pdbutil
Add llvm-pdbutil to run-make-support, so we can write better unit tests for PDB specific features.

Use sysroot crates maximally in `rustc_codegen_gcc`.
This shrinks `compiler/rustc_codegen_gcc/Cargo.lock` quite a bit. The only remaining dependencies in `compiler/rustc_codegen_gcc/Cargo.lock` are `gccjit`, `lang_tester`, and `boml`, all of which aren't used in any other compiler crates.
The commit also reorders and adds comments to the `extern crate` items so they match those in miri.

rustdoc: normalise type/field names
Updates #100961
- `Import` -> `Use`, to better reflect the terminology of Rust & its syntax
- `TypeBinding` -> `AssocItemConstraint`, to sync up with `clean`
- `FnDecl` -> `FunctionSignature`, because that's what it is
- `Header` -> `FunctionHeader`, because `Header` is a very word that's very heavily loaded with different meanings
- `ItemEnum::AssocType`: `default` -> `type`, because those items appear in `impl` blocks as well, where they're _not_ the "default"
- `ItemEnum::AssocConst`: `default` -> `value`, see the previous point
- `ForeignType` -> `ExternType`, because "foreign" is not the right word there
- boolean fields' names made to consistently be a phrase that can be a yes/no answer, e.g. `async` -> `is_async`
The docs of `ItemEnum::AssocType::type_` & of `ItemEnum::AssocConst::value` are also updated to be up to date with the clarification of the name of the fields
Use the same code as Solaris. I couldn't find any tests regarding this, but I
did test a stage0 build against my stack-exhaust-test binary [1]. Before:
```
running with use_stacker = No, new_thread = false, make_large_local = false
zsh: segmentation fault (core dumped) cargo run
```
After:
```
running with use_stacker = No, new_thread = false, make_large_local = false
thread 'main' has overflowed its stack
fatal runtime error: stack overflow
zsh: IOT instruction (core dumped) cargo +stage0 run
```
Fixes#128568.

detect incompatible CI LLVM options more precisely
Previously, the logic here was simply checking whether the option was set in `config.toml`. This approach was not manageable in our CI runners as we set so many options in config.toml. In reality, those values are not incompatible since they are usually the same value used to generate the CI llvm. Now, the new logic compares the configuration values with the values used to generate the CI llvm, so we get more precise results and make the process more manageable.
Fixes#129153
It's a very thin wrapper that pairs `MoveDataBuilder` with a `Location`,
and it has four lifetime arguments. This commit removes it by just
adding a `Location` to `MoveDataBuilder`.
