remove support for rustc_safe_intrinsic attribute; use rustc_intrinsic functions instead
This brings us one step closer towards removing support for `extern "rust-intrinsic"` blocks, in favor of `#[rustc_intrinsic]` functions.
Also move `#[rustc_intrinsic]` under the `intrinsics` feature gate, to match the `extern "rust-intrinsic"` style.

Initialize channel `Block`s directly on the heap
The channel's `Block::new` was causing a stack overflow because it held
32 item slots, instantiated on the stack before moving to `Box::new`.
The 32x multiplier made modestly-large item sizes untenable.
That block is now initialized directly on the heap.
Fixes #102246

Simplify FFI calls for `-Ztime-llvm-passes` and `-Zprint-codegen-stats`
The existing code for these unstable LLVM-infodump flags was jumping through hoops to pass an allocated C string across the FFI boundary, when it's much simpler to just write to a `&RustString` instead.

coverage: Extract safe FFI wrapper functions to `llvm_cov`
This PR takes all of the inline `unsafe` calls in coverage codegen, and all the safe wrapper functions in `coverageinfo/mod.rs`, and moves them to a new `llvm_cov` submodule that is dedicated to safe FFI wrapper functions. This reduces the mixing of abstraction levels in the rest of coverage codegen.
As a follow-up, this PR also tidies up the names and signatures of several of the coverage FFI functions.

coverage: Simplify parts of coverage graph creation
This is a combination of three semi-related simplifications to how coverage graphs are created, grouped into one PR to avoid conflicts.
There are no observable changes to the output of any of the coverage tests.

Not actually sure why, but sometimes the PID isn't available so we print

This originated from the `test_num_f128` test not having the required conditional compilation. This PR fixes that issue.

core: move intrinsics.rs into intrinsics folder
This makes the rustbot notification we have set up for this folder in `triagebot.toml` actually work. Also IMO it makes more sense to have it all in one folder.

[StableMIR] API to retrieve definitions from crates
Add functions to retrieve function definitions and static items from all crates (local and external).
For external crates, we're still missing items from trait implementation and primitives.

Fix #131977 parens mangled in shared mut static lint suggestion
Resolves #131977 for static mut references after discussion with
Esteban & Jieyou on [t-compiler/help](https://rust-lang.zulipchat.com/#narrow/channel/182449-t-compiler.2Fhelp/topic/linting.20with.20parens.20in.20the.20HIR).
This doesn't do anything to change the underlying issue if there are other expressions that generate lint suggestions which need to be applied within parentheses.

Add `{ignore,needs}-{rustc,std}-debug-assertions` directive support
Add `{ignore,needs}-{rustc,std}-debug-assertions` compiletest directives and retire the old `{ignore,only}-debug` directives. The old `{ignore,only}-debug` directives were ambiguous because you could have std built with debug assertions but rustc not built with debug assertions or vice versa. If we want to support the use case of controlling test run based on if rustc was built with debug assertions, then having `{ignore,only}-debug` will be very confusing.

Closes #123987.

Set "symbol name" in raw-dylib import libraries to the decorated name
`windows-rs` received a bug report that mixing raw-dylib generated and the Windows SDK import libraries was causing linker failures: <https://github.com/microsoft/windows-rs/issues/3285>
The root cause turned out to be #124958, that is we are not including the decorated name in the import library and so the import name type is also not being correctly set.
This change modifies the generation of import libraries to set the "symbol name" to the fully decorated name and correctly marks the import as being data vs function.
Note that this also required some changes to how the symbol is named within Rust: for MSVC we now need to use the decorated name but for MinGW we still need to use partially decorated (or undecorated) name.
Fixes #124958
Passing i686 MSVC and MinGW build: <https://github.com/rust-lang/rust/actions/runs/11000433888?pr=130586>

Tweak detection of multiple crate versions to be more encompassing
Previously, we only emitted the additional context if the type was in the same crate as the trait that appeared multiple times in the dependency tree. Now, we look at all traits looking for two with the same name in different crates with the same crate number, and we are more flexible looking for the types involved. This will work even if the type that implements the wrong trait version is from a different crate entirely.

Basic inline assembly support for SPARC and SPARC64
This implements asm_experimental_arch (tracking issue https://github.com/rust-lang/rust/issues/93335) for SPARC and SPARC64.
This PR includes:
- General-purpose registers `r[0-31]` (`reg` register class, LLVM/GCC constraint `r`)
Supported types: i8, i16, i32, i64 (SPARC64-only)
Aliases: `g[0-7]` (`r[0-7]`), `o[0-7]` (`r[8-15]`), `l[0-7]` (`r[16-23]`), `i[0-7]` (`r[24-31]`)
- `y` register (clobber-only, needed for clobber_abi)
- preserves_flags: Integer condition codes (`icc`, `xcc`) and floating-point condition codes (`fcc*`)
The following are *not* included:
- 64-bit integer support on SPARC-V8+'s global or out registers (`g[0-7]`, `o[0-7]`): GCC's `h` constraint (it seems that there is no corresponding constraint in LLVM?)
- Floating-point registers (LLVM/GCC constraint `e`/`f`):
I initially tried to implement this, but postponed it for now because there seemed to be several parts in LLVM that behaved differently than in the LangRef's description.
- clobber_abi: Support for floating-point registers is needed.

The approach to accomplish this is a HACK, and we'd want a better way to do this. I believe that moving E0277 to be a structured diagnostic would help in that regard.
