This updates all places where match branches check on StatementKind or UseContext.
This doesn't properly implement them, but adds TODOs where they are, and also adds some best
guesses to what they should be in some cases.

I'm still not totally sure if this is the right way to implement the memcpy, but that portion
compiles correctly now. Now to fix the compile errors everywhere else :).
Fix ICE 6840 - make is_normalizable more strict
fixes#6840
make `is_normalizable` more strict, which should catch this ICE and related cases
changelog: Fix ICE in [`zero_sized_map_values`]
Refactor casts lint
Ref: #6724
Changes:
1. Separate the `casts` group from the `types` group.
2. Reorganize the lints of the `casts` group into their own modules.
Notes:
1. I didn't `fix` #6874 in order to maintain this PR as small as possible.

Update CONTRIBUTING.md
Fixes#77215
As mentioned in #77215, the current CONTRIBUTING.md links to the rustc-dev-guide.
Even though the rustc-dev-guide has lots of useful information for contributors,
one is already confused by reading the first line of the current CONTRIBUTING.md.
> To get started, read the [Getting Started] guide in the [rustc-dev-guide].
This line tells the contributor to go and read the rustc-dev-guide. What is
the rustc-dev-guide? What does rustc even mean? These are some of the
questions that went into my head when reading this line as a first-time
contributor. By explaining what the rustc-dev-guide is and some platforms
to get help, a new contributor understands what the first step is and the process
is much clearer. The `About the [rustc-dev-guide]` section explains what
the rustc-dev-guide is, what rustc is, and the purpose out of reading the
guide. The `Getting help` section points the user to some places where
they can get help, find a mentor, and introduce themselves.

Change x64 size checks to not apply to x32.
Rust contains various size checks conditional on target_arch = "x86_64", but these checks were never intended to apply to x86_64-unknown-linux-gnux32. Add target_pointer_width = "64" to the conditions.
or-patterns: disallow in `let` bindings
~~Blocked on https://github.com/rust-lang/rust/pull/81869~~
Disallows top-level or-patterns before type ascription. We want to reserve this syntactic space for possible future generalized type ascription.

Added #[repr(transparent)] to core::cmp::Reverse
I found casting from an `&T` to an `&Reverse<T>` potentially useful, but found that `Reverse` was not `#[repr(transparent)]`, so after asking about it [on Reddit](https://www.reddit.com/r/rust/comments/le60uv/make_stdcmpreverse_reprtransparent_and_add_a/), I decided to go ahead and make a pull request which simply adds the attribute to the struct.
Improve sift_down performance in BinaryHeap
Replacing `child < end - 1` with `child <= end.saturating_sub(2)` in `BinaryHeap::sift_down_range` (surprisingly) results in a significant speedup of `BinaryHeap::into_sorted_vec`. The same substitution can be done for `BinaryHeap::sift_down_to_bottom`, which causes a slight but probably statistically insignificant speedup for `BinaryHeap::pop`. It's interesting that benchmarks aside from `bench_into_sorted_vec` are barely affected, even those that do use `sift_down_*` methods internally.
| Benchmark | Before (ns/iter) | After (ns/iter) | Speedup |
|--------------------------|------------------|-----------------|---------|
| bench_find_smallest_1000<sup>1</sup> | 392,617 | 385,200 | 1.02 |
| bench_from_vec<sup>1</sup> | 506,016 | 504,444 | 1.00 |
| bench_into_sorted_vec<sup>1</sup> | 476,869 | 384,458 | 1.24 |
| bench_peek_mut_deref_mut<sup>3</sup> | 518,753 | 519,792 | 1.00 |
| bench_pop<sup>2</sup> | 446,718 | 444,409 | 1.01 |
| bench_push<sup>3</sup> | 772,481 | 770,208 | 1.00 |
<sup>1</sup>: internally calls `sift_down_range`
<sup>2</sup>: internally calls `sift_down_to_bottom`
<sup>3</sup>: should not be affected
