[Coverage][MCDC] Adapt mcdc to llvm 19
Related issue: #126672
Also finish task 4 at #124144
[llvm #82448 ](https://github.com/llvm/llvm-project/pull/82448 ) has introduced some break changes into mcdc, causing incompatibility between llvm 18 and 19. This draft adapts to that change and gives up supporting for llvm-18.

Add missing module flags for `-Zfunction-return=thunk-extern`
This fixes a bug in the `-Zfunction-return=thunk-extern` flag. The flag needs to be passed onto LLVM to ensure that functions such as `asan.module_ctor` and `asan.module_dtor` that are created internally in LLVM have the mitigation applied to them.
This was originally discovered [in the Linux kernel](https://lore.kernel.org/all/CANiq72myZL4_poCMuNFevtpYYc0V0embjSuKb7y=C+m3vVA_8g@mail.gmail.com/ ).

Rollup merge of #130630 - taiki-e:s390x-clobber-abi, r=Amanieu
...
Support clobber_abi and vector/access registers (clobber-only) in s390x inline assembly
This supports `clobber_abi` which is one of the requirements of stabilization mentioned in #93335 .
This also supports vector registers (as `vreg`) and access registers (as `areg`) as clobber-only, which need to support clobbering of them to implement clobber_abi.
Refs:
- "1.2.1.1. Register Preservation Rules" section in ELF Application Binary Interface s390x Supplement, Version 1.6.1 (lzsabi_s390x.pdf in https://github.com/IBM/s390x-abi/releases/tag/v1.6.1 )
- Register definition in LLVM:
- Vector registers https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/SystemZ/SystemZRegisterInfo.td#L249
- Access registers https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/SystemZ/SystemZRegisterInfo.td#L332
I have three questions:
- ~~ELF Application Binary Interface s390x Supplement says that `cc` (condition code, bits 18-19 of PSW) is "Volatile".
However, we do not have a register class for `cc` and instead mark `cc` as clobbered unless `preserves_flags` is specified (https://github.com/rust-lang/rust/pull/111331 ).
Therefore, in the current implementation, if both `preserves_flags` and `clobber_abi` are specified, `cc` is not marked as clobbered. Is this okay? Or even if `preserves_flags` is used, should `cc` be marked as clobbered if `clobber_abi` is used?~~ UPDATE: resolved https://github.com/rust-lang/rust/pull/130630#issuecomment-2367923121
- ~~ELF Application Binary Interface s390x Supplement says that `pm` (program mask, bits 20-23 of PSW) is "Cleared".
There does not appear to be any registers associated with this in either [LLVM](https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/SystemZ/SystemZRegisterInfo.td ) or [GCC](33ccc1314d/gcc/config/s390/s390.h (L407-L431)https://github.com/rust-lang/rust/pull/130630#issuecomment-2367923121
- Is "areg" a good name for register class name for access registers? It may be a bit confusing between that and `reg_addr`, which uses the “a” constraint (https://github.com/rust-lang/rust/pull/119431 )...
Note:
- GCC seems to [recognize only `a0` and `a1`](33ccc1314d/gcc/config/s390/s390.h (L428-L429)https://godbolt.org/z/a46vx8jjn ).
Given that cg_gcc has a similar problem with other architecture (https://github.com/rust-lang/rustc_codegen_gcc/issues/485 ), I don't feel this is a blocker for this PR, but it is worth mentioning here.
- `vreg` should be able to accept `#[repr(simd)]` types as input if the `vector` target feature added in https://github.com/rust-lang/rust/pull/127506 is enabled, but core_arch has no s390x vector type and both `#[repr(simd)]` and `core::simd` are unstable, so I have not implemented it in this PR. EDIT: And supporting it is probably more complex than doing the equivalent on other architectures... https://github.com/rust-lang/rust/pull/88245#issuecomment-905559591

rustc_target: Add RISC-V atomic-related features
This adds the following three target features to unstable riscv_target_feature.
- `zaamo` (Zaamo Extension 1.0.0): Atomic Memory Operations (`amo*.{w,d}{,.aq,.rl,.aqrl}`)
([definition in LLVM](https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/RISCV/RISCVFeatures.td#L229-L231 ), [available since LLVM 19](8be079cdddhttps://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/RISCV/RISCVFeatures.td#L238-L240 ), [available since LLVM 19](6b7444964ahttps://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/RISCV/RISCVFeatures.td#L261-L263 ), [available since LLVM 19](8be079cddd70e7d26e56614aeda93be87412e62108693e29ec/gcc/config/riscv/arch-canonicalize (L44)https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/RISCV/RISCVFeatures.td#L206 ).
- Zabha and Zaamo are in a similar situation, [riscv-isa-manual](https://github.com/riscv/riscv-isa-manual/blob/main/src/zabha.adoc ) says "The Zabha extension depends upon the Zaamo standard extension", and [`zabha` implies `zaamo` in GCC](08693e29ec/gcc/config/riscv/arch-canonicalize (L45-L46)https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/TargetParser/RISCVISAInfo.cpp#L776-L778 ).

Bump stage0 to beta-2024-09-22 and rustfmt to nightly-2024-09-22
I'm doing this to apply the changes to version sorting (https://github.com/rust-lang/rustfmt/pull/6284 ) that have occurred since rustfmt last upgraded (and a few other miscellaneous changes, like changes to expression overflowing: https://github.com/rust-lang/rustfmt/pull/6260 ). Eagerly updating rustfmt and formatting-the-world will ideally move some of the pressure off of the beta bump which will happen at the beginning of the next release cycle.
You can verify this is correct by checking out the changes, reverting the last commit, reapplying them, and diffing the changes:
```
git fetch git@github.com:compiler-errors/rust.git bump
git checkout -b bump FETCH_HEAD
git reset --hard HEAD~5
./x.py fmt --all
git diff FETCH_HEAD
# ignore the changes to stage0, and rustfmt.toml,
# and test file changes in rustdoc-js-std, run-make.
```
Or just take my word for it? Up to the reviewer.

Streamline hidden visibility setting.
...
In `get_fn` there is a complicated set of if/elses to determine if
`hidden` visibility should be applied. There are five calls to
`LLVMRustSetVisibility` and some repetition in the comments.
This commit streamlines it a bit:
- Computes `hidden` and then uses it to determine if a single call to
`LLVMRustSetVisibility` occurs.
- Converts some of the if/elses into boolean expressions.
- Removes the repetitive comments.
Overall this makes it quite a bit shorter, and I find it easier to read.
