Some promotion cleanup

Based on top of both https://github.com/rust-lang/rust/pull/75502 and https://github.com/rust-lang/rust/pull/75585, this does some cleanup of the promotion code. The last 2 commits are new.

* Remove the remaining cases where `const fn` is treated different from `fn`. This means no longer promoting ptr-to-int casts, raw ptr operations, and union field accesses in `const fn` -- or anywhere, for that matter. These are all unstable in const-context so this should not break any stable code. Fixes https://github.com/rust-lang/rust/issues/75586.
* ~~Promote references to statics even outside statics (i.e., in functions) for consistency.~~
* Promote `&mut []` everywhere, not just in non-`const` functions, for consistency.
* Explain why we do not promote deref's of statics outside statics. ~~(This is the only remaining direct user of `const_kind`.)~~

This can only land once the other two PRs land; I am mostly putting this up already because I couldn't wait ;) and to get some feedback from `@rust-lang/wg-const-eval` .

shim: monomorphic `FnPtrShim`s during construction

Fixes #69925.

This PR adjusts MIR shim construction so that substitutions are applied to function pointer shims during construction, rather than during codegen (as determined by `substs_for_mir_body`).

Implement a generic Destination Propagation optimization on MIR

This takes the work that was originally started by `@eddyb` in https://github.com/rust-lang/rust/pull/47954, and then explored by me in https://github.com/rust-lang/rust/pull/71003, and implements it in a general (ie. not limited to acyclic CFGs) and dataflow-driven way (so that no additional infrastructure in rustc is needed).

The pass is configured to run at `mir-opt-level=2` and higher only. To enable it by default, some followup work on it is still needed:
* Performance needs to be evaluated. I did some light optimization work and tested against `tuple-stress`, which caused trouble in my last attempt, but didn't go much in depth here.
  * We can also enable the pass only at `opt-level=2` and higher, if it is too slow to run in debug mode, but fine when optimizations run anyways.
* Debuginfo needs to be fixed after locals are merged. I did not look into what is required for this.
* Live ranges of locals (aka `StorageLive` and `StorageDead`) are currently deleted. We either need to decide that this is fine, or if not, merge the variable's live ranges (or remove these statements entirely – https://github.com/rust-lang/rust/issues/68622).

Some benchmarks of the pass were done in https://github.com/rust-lang/rust/pull/72635.

10d272b2e2 Update Clippy testcases
Update the test `redundant_pattern_matching`: check if `is_ok` and `is_err` are suggested within const contexts.
Also removes the `redundant_pattern_matching_const_result` test, as it is no longer needed.

389b7ff190 Do not link LLVM tools to LLVM dylib unless rustc is
Previously we would have some platforms where LLVM was linked to rustc
statically, but to the LLVM tools dynamically. That meant we were distributing
two copies of LLVM: one as a separate dylib and one statically linked in to
librustc_driver.

59fb88d061 Auto merge of #76327 - lzutao:split-core-num, r=SimonSapin
Split `core/num/mod.rs` to smaller mods

Note for reviewer:
* I split to multiple commits for easier reviewing, but I could git squash them all to one if requested.
* Recommend pulling this change locally and using advanced git diff viewer or this command:
  ```
  git show --reverse --color-moved=dimmed-zebra master..
  ```

---

I split `core/num/mod.rs` to these modules:

* `error`: For error structs like `ParseIntError`.
* blanket `shells` dir: For dummy number type modules: std::i32, std::f32, and the likes. Why? See below.
* `int_macros` and `uint_macros`: Real implementation of all integer types via `int_impl` and `uint_impl`
* `nonzero`: For `NonZero*` types and their implementations.
* `wrapping`: For `Wrapping<T>` types.
