A more robust solution to finding where to place use suggestions was added.
The algorithm uses the AST to find the span for the suggestion so we pass this span
down to the HIR during lowering and use it.

Signed-off-by: Miguel Guarniz <[email protected]>
The docs for `Iterator::unzip` explain that it is kind of an inverse operation to `Iterator::zip` and guide the reader to the `zip` docs, but the `zip` docs don't let the user know that they can undo the `zip` operation with `unzip`. This change modifies the docs to help the user find `unzip`.

Stabilize `derive_default_enum`

This stabilizes `#![feature(derive_default_enum)]`, as proposed in [RFC 3107](rust-lang/rfcs#3107) and tracked in rust-lang#87517. In short, it permits you to `#[derive(Default)]` on `enum`s, indicating what the default should be by placing a `#[default]` attribute on the desired variant (which must be a unit variant in the interest of forward compatibility).

Implement sym operands for global_asm!

Tracking issue: rust-lang#93333

This PR is pretty much a complete rewrite of `sym` operand support for inline assembly so that the same implementation can be shared by `asm!` and `global_asm!`. The main changes are:
- At the AST level, `sym` is represented as a special `InlineAsmSym` AST node containing a path instead of an `Expr`.
- At the HIR level, `sym` is split into `SymStatic` and `SymFn` depending on whether the path resolves to a static during AST lowering (defaults to `SynFn` if `get_early_res` fails).
  - `SymFn` is just an `AnonConst`. It runs through typeck and we just collect the resulting type at the end. An error is emitted if the type is not a `FnDef`.
  - `SymStatic` directly holds a path and the `DefId` of the `static` that it is pointing to.
- The representation at the MIR level is mostly unchanged. There is a minor change to THIR where `SymFn` is a constant instead of an expression.
- At the codegen level we need to apply the target's symbol mangling to the result of `tcx.symbol_name()` depending on the target. This is done by calling the LLVM name mangler, which handles all of the details.
  - On Mach-O, all symbols have a leading underscore.
  - On x86 Windows, different mangling is used for cdecl, stdcall, fastcall and vectorcall.
  - No mangling is needed on other platforms.

remove find_use_placement

A more robust solution to finding where to place use suggestions was added in rust-lang#94584.
The algorithm uses the AST to find the span for the suggestion so we pass this span
down to the HIR during lowering and use it instead of calling `find_use_placement`

docs: add link from zip to unzip

The docs for `Iterator::unzip` explain that it is kind of an inverse operation to `Iterator::zip` and guide the reader to the `zip` docs, but the `zip` docs don't let the user know that they can undo the `zip` operation with `unzip`. This change modifies the docs to help the user find `unzip`.
Use u32 instead of i32 for futexes.

This changes futexes from i32 to u32. The [Linux man page](https://man7.org/linux/man-pages/man2/futex.2.html) uses `uint32_t` for them, so I'm not sure why I used i32 for them. Maybe because I first used them for thread parkers, where I used -1, 0, and 1 as the states.

(Wasm's `memory.atomic.wait32` does use `i32`, because wasm doesn't support `u32`.)

It doesn't matter much, but using the unsigned type probably results in fewer surprises when shifting bits around or using comparison operators.

# FIXME(richkadel): None of the Rust test source samples have the
# `// ignore-llvm-cov-show-diffs` anymore. This directive exists to work around a limitation
# with `llvm-cov show`. When reporting coverage for multiple instantiations of a generic function,
# with different type substitutions, `llvm-cov show` prints these in a non-deterministic order,
# breaking the `diff` comparision.
#
# A partial workaround is implemented below, with `diff --ignore-matching-lines=RE`
# to ignore each line prefixing each generic instantiation coverage code region.
#
# This workaround only works if the coverage counts are identical across all reported
# instantiations. If there is no way to ensure this, you may need to apply the
# `// ignore-llvm-cov-show-diffs` directive, and check for differences using the
# `.json` files to validate that results have not changed. (Until then, the JSON
# files are redundant, so there is no need to generate `expected_*.json` files or

-   67|       |//
-   68|       |// These notices appear when `llvm-cov` shows instantiations. This may be a
-   69|       |// default option, but it can be suppressed with:
-   70|       |//
-   71|       |// ```shell
-   72|       |// $ `llvm-cov show --show-instantiations=0 ...`
-   73|       |// ```
-   74|       |//
-   75|       |// The notice is triggered because the function is unused by the library itself,
-   76|       |// and when the library is compiled, a synthetic function is generated, so
-   77|       |// unused function coverage can be reported. Coverage can be skipped for unused
-   78|       |// generic functions with:
-   79|       |//
-   80|       |// ```shell
-   81|       |// $ `rustc -Zunstable-options -C instrument-coverage=except-unused-generics ...`
-   82|       |// ```
-   83|       |//
-   84|       |// Even though this function is used by `uses_crate.rs` (and
-   85|       |// counted), with substitutions for `T`, those instantiations are only generated
-   86|       |// when the generic function is actually used (from the binary, not from this
-   87|       |// library crate). So the test result shows coverage for all instantiated
-   88|       |// versions and their generic type substitutions, plus the `Unexecuted
-   89|       |// instantiation` message for the non-substituted version. This is valid, but
-   90|       |// unfortunately a little confusing.
-   91|       |//
-   92|       |// The library crate has its own coverage map, and the only way to show unused
-   93|       |// coverage of a generic function is to include the generic function in the
-   94|       |// coverage map, marked as an "unused function". If the library were used by
-   95|       |// another binary that never used this generic function, then it would be valid
-   96|       |// to show the unused generic, with unknown substitution (`_`).
-   97|       |//
-   98|       |// The alternative is to exclude all generics from being included in the "unused
-   99|       |// functions" list, which would then omit coverage results for
-  100|       |// `unused_generic_function<T>()`, below.
