While trying to enable riscv64gc in https://github.com/rust-lang/rust/pull/125669, I noticed several tests failing in https://github.com/rust-lang/rust/actions/runs/9454116367/job/26040977376. I spoke a bit with `@pietroalbini` and he recommended this approach to resolving the issue.
This PR interacts with https://github.com/rust-lang/rust/pull/126279, and it is likely preferable that https://github.com/rust-lang/rust/pull/126279 merges and my changes in ae769f930e2510e57ed8bd379b1b2d393b2312c3 get removed from this PR.
## Testing
> [!NOTE]
> `riscv64gc-unknown-linux-gnu` is a [**Tier 2 with Host Tools** platform](https://doc.rust-lang.org/beta/rustc/platform-support.html), all tests may not necessarily pass! There is work in https://github.com/rust-lang/rust/pull/125220 which helps fix several related tests.
You can test out the renamed job:
```sh
DEPLOY=1 ./src/ci/docker/run.sh riscv64gc-gnu
```
`DEPLOY=1` helps reproduce the CI's environment and also avoids the chance of a `llvm-c/BitReader.h` error (detailed in https://github.com/rust-lang/rust/issues/85424 and https://github.com/rust-lang/rust/issues/56650).

Consistently use subtyping in method resolution

Convert a `span_bug` to a `span_delayed_bug`.
PR #121208 converted this from a `span_delayed_bug` to a `span_bug` because nothing in the test suite caused execution to hit this path. But now fuzzing has found a test case that does hit it. So this commit converts it back to `span_delayed_bug` and adds the relevant test.

Make suggestion to change `Fn` to `FnMut` work with methods as well

The issue occurred because the code that emitted the suggestion to change `Fn` to `FnMut` worked only for function calls and not method calls. This PR makes it work with methods as well.

Resolve elided lifetimes in assoc const to static if no other lifetimes are in scope
Implements the change to elided lifetime resolution in *associated consts* subject to FCP here: https://github.com/rust-lang/rust/issues/125190#issue-2301532282
Specifically, walk the enclosing lifetime ribs in an associated const, and if we find no other lifetimes, then resolve to `'static`.
Also make it work for traits, but don't lint -- just give a hard error in that case.

Remove superfluous UbChecks from `SliceIndex` methods
The current implementation calls the unsafe ones from the safe ones, but that means they end up emitting UbChecks that are impossible to hit, since we just checked those things.
This PR adds some new module-local helpers for the code shared between them, so the safe methods can be small enough to inline by avoiding those extra checks, while the unsafe methods still help catch length mistakes.

tests/ui/lint: Move 19 tests to new `non-snake-case` subdir
Mainly so that it is easier to only run all `non_snake_case`-lint-specific tests with:
./x test tests/ui/lint/non-snake-case
But also to reduce the size of the large `tests/ui/lint` directory. And rename some tests to pass tidy, and remove them from `src/tools/tidy/src/issues.txt`.

smir: merge identical Constant and ConstOperand types
The first commit renames the const operand visitor functions on regular MIR to match the type name, that was forgotten in the original rename.
The second commit changes stable MIR, fixing https://github.com/rust-lang/project-stable-mir/issues/71. Previously there were two different smir types for the MIR type `ConstOperand`, one used in `Operand` and one in `VarDebugInfoContents`.
Maybe we should have done this with https://github.com/rust-lang/rust/pull/125967, so there's only a single breaking change... but I saw that PR too late.
Fixes https://github.com/rust-lang/project-stable-mir/issues/71

Check that alias-relate terms are WF if reporting an error in alias-relate
Check that each of the left/right term is WF when deriving a best error obligation for an alias-relate goal. This will make sure that given `<i32 as NotImplemented>::Assoc = ()` will drill down into `i32: NotImplemented` since we currently treat the projection as rigid.

Add `f16` and `f128` const eval for binary and unary operationations
Add const evaluation and Miri support for f16 and f128, including unary and binary operations. Casts are not yet included.

Add `f16` and `f128` inline ASM support for `x86` and `x86-64`
This PR adds `f16` and `f128` input and output support to inline ASM on `x86` and `x86-64`. `f16` vector sizes are taken from [here](https://www.intel.com/content/www/us/en/docs/intrinsics-guide/index.html).
Relevant issue: #125398

Unify intrinsics body handling in StableMIR
rust-lang/rust#120675 introduced a new mechanism to declare intrinsics which will potentially replace the rust-intrinsic ABI.
The new mechanism introduces a placeholder body and mark the intrinsic with `#[rustc_intrinsic_must_be_overridden]`.
In practice, this means that a backend should not generate code for the placeholder, and shim the intrinsic.
The new annotation is an internal compiler implementation, and it doesn't need to be exposed to StableMIR users.
In this PR, we unify the interface for intrinsics marked with `rustc_intrinsic_must_be_overridden` and intrinsics that do not have a body.
Fixes https://github.com/rust-lang/project-stable-mir/issues/79

delegation: Fix hygiene for `self`
And fix diagnostics for `self` from a macro.
The missing rib caused `self` to be treated as a generic parameter and ignore `macro_rules` hygiene.
Addresses this comment https://github.com/rust-lang/rust/pull/124135#discussion_r1637492234.

Based on top of #125289, so just need to look at the last commit.

Don't build a broken/untested profiler runtime on mingw targets
Context: https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Why.20build.20a.20broken.2Funtested.20profiler.20runtime.20on.20mingw.3F
#75872 added `--enable-profiler` to the `x86_64-mingw` job (to cause some additional tests to run), but had to also add `//@ ignore-windows-gnu` to all of the tests that rely on the profiler runtime actually *working*, because it's broken on that target.
We can achieve a similar outcome by going through all the `//@ needs-profiler-support` tests that don't actually need to produce/run a binary, and making them use `-Zno-profiler-runtime` instead, so that they can run even in configurations that don't have the profiler runtime available. Then we can remove `--enable-profiler` from `x86_64-mingw`, and still get the same amount of testing.
This PR also removes `--enable-profiler` from the mingw dist builds, since it is broken/untested on that target. Those builds have had that flag for a very long time.

Const eval negation was added. This test is now covered by Miri tests,
and merged into an existing UI test.

Add a new concat metavar expr
Revival of #111930
Giving it another try now that #117050 was merged.
With the new rules, meta-variable expressions must be referenced with a dollar sign (`$`) and this can cause misunderstands with `$concat`.
```rust
macro_rules! foo {
( $bar:ident ) => {
const ${concat(VAR, bar)}: i32 = 1;
};
}
// Will produce `VARbar` instead of `VAR_123`
foo!(_123);
```
In other words, forgetting the dollar symbol can produce undesired outputs.
