Rework `feature(precise_capturing)` to represent `use<...>` as a syntactical bound
Reworks `precise_capturing` for a recent lang-team consensus.
Specifically:
> The conclusion of the team is that we'll make use<..> a bound. That is, we'll support impl use<..> + Trait, impl Trait + use<..>, etc.
> For now, we will support at most one such bound in a list of bounds, and semantically we'll only support these bounds in the item bounds of RPIT-like impl Trait opaque types (i.e., in the places discussed in the RFC).
Lang decision in favor of this approach:
- https://github.com/rust-lang/rust/issues/125836#issuecomment-2151351849
Tracking:
- https://github.com/rust-lang/rust/issues/123432
Return opaque type from PanicInfo::message()
This changes the return type of the (unstable) PanicInfo::message() method to an opaque type (that implements Display). This allows for a bit more flexibility in the future.

Migrate `link-arg`, `link-dedup` and `issue-26092` `run-make` tests to `rmake` format
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
All of these tests check if rustc's output contains (or does not) contain certain strings. Does that mean these could be better suited to becoming UI/codegen tests?

Rename `InstanceDef` -> `InstanceKind`
Renames `InstanceDef` to `InstanceKind`. The `Def` here is confusing, and makes it hard to distinguish `Instance` and `InstanceDef`. `InstanceKind` makes this more obvious, since it's really just describing what *kind* of instance we have.
Not sure if this is large enough to warrant a types team MCP -- it's only 53 files. I don't personally think it does, but happy to write one if anyone disagrees. cc ``@rust-lang/types``

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).

fix checking git submodules during a commit hook
Fixes https://github.com/rust-lang/rust/issues/125954
The one thing that still puzzles me is why this only is a problem with worktrees.
r? `@onur`
This synchronizes the fuchsia test running code with the clang test
runner. This brings with it:
* Improved logging
* Uses the fuchsia image from the SDK version
* Caches the product bundle across test runs
* Strips the binaries to reduce the data sent to the emulator

Consistently use subtyping in method resolution
fixes#126062
An earlier version of this PR modified how we compute variance, but the root cause was an inconsistency between the usage of `eq` and `sub`, where we assumed that the latter passing implies the former will pass.

When set, this flag skips the code that normally extracts coverage spans from
MIR statements and terminators. That sometimes makes it easier to debug branch
coverage and MC/DC coverage, because the coverage output is less noisy.
For internal debugging only. If other code changes would make it hard to keep
supporting this flag, remove it.
