structural_match: non-structural-match ty closures
This commit adds a `Closure` variant to `NonStructuralMatchTy` in
`structural_match`, fixing an ICE which can occur when
`impl_trait_in_bindings` is used with constants.

x.py: do not build Miri by default on stable/beta

Fixes https://github.com/rust-lang/rust/issues/73117

Do I need to do anything to make sure Miri is still built by the tools CI builder? Are there other tools that should be off-by-default?

Also, unfortunately the `DEFAULT` associated const has no doc comment, so I have no idea what it does, or why there are semmingly two places where the default build of tools is controlled.

Rollup merge of #73267 - ehuss:cargotest-this-cargo, r=Mark-Simulacrum
Use the built cargo for cargotest.

cargotest was using the beta (bootstrap) cargo. This changes it so that it will use the locally built cargo. This is intended to provide a sort of smoke test to ensure Cargo is functional. This *shouldn't* have any real impact on the CI build time.  The cargotest job also happens to run cargo's testsuite, so it should already be building cargo.

Note: This will fail until #73266 is merged.

Querify whether a type has structural equality (Take 2)

Alternative to #72177.

Unlike in #72177, this helper method works for all types, falling back to a query for `TyKind::Adt`s that determines whether the `{Partial,}StructuralEq` traits are implemented.

This is my preferred interface for this method. I think this is better than just documenting that the helper only works for ADTs. If others disagree, we can just merge #72177 with the fixes applied. This has already taken far too long.

3ab4b380aa Adjusted some doctests in libcore to use should_panic.
Previously, some doctests were spawning new threads and joining them to
indicate that a particular call should panic; this hurt readability, so
the tests have been adjusted to simply call the method and use the
`should_panic` marker.

expand: More precise locations for expansion-time lints

First commit: a macro expansion doesn't have a `NodeId` associated with it, but it has a parent `DefId` which we can use for linting.
The observable effect is that lints associated with macro expansions can now be `allow`ed at finer-grained level than whole crate.

Second commit: each macro definition has a `NodeId` which we can use for linting, unless that macro definition was decoded from other crate.

Provide suggestion to convert numeric op LHS rather than unwrapping RHS

Given a code

```rust
fn foo(x: u8, y: u32) -> bool {
    x > y
}
fn main() {}
```

it could be more helpful to provide a suggestion to do "u32::from(x)"
rather than "y.try_into().unwrap()", since the latter may panic.

We do this by passing the LHS of a binary expression up the stack into
the coercion checker.

std: Enable atomic.fence emission on wasm32

This commit removes the `#[cfg]` guards in `atomic::fence` on wasm
targets. Since these guards were originally added the upstream wasm
specification for threads gained an `atomic.fence` instruction, so LLVM
no longer panics on these intrinsics.

Although there aren't a ton of tests in-repo for this right now I've
tested locally and all of these fences generate `atomic.fence`
instructions in wasm.

Fix #[thread_local] statics as asm! sym operands

The `asm!` RFC specifies that `#[thread_local]` statics may be used as `sym` operands for inline assembly.

This also fixes a regression in the handling of `#[thread_local]` during monomorphization which caused link-time errors with multiple codegen units, most likely introduced by #71192.

Rollup merge of #73230 - Amanieu:asm-unused2, r=petrochenkov
Suggest including unused asm arguments in a comment to avoid error

We require all arguments to an `asm!` to be used in the template string, just like format strings. However in some cases (e.g. `black_box`) it may be desirable to have `asm!` arguments that are not used in the template string.

Currently this is a hard error rather than a lint since `#[allow]` does not work on macros (#63221), so this PR suggests using the unused arguments in an asm comment as a workaround.
