Add a Lint for Pointer to Integer Transmutes in Consts

Fixes #87525

This PR adds a MirLint for pointer to integer transmutes in const functions and associated consts. The implementation closely follows this comment: https://github.com/rust-lang/rust/pull/85769#issuecomment-880969112. More details about the implementation can be found in the comments.

Note: This could break some sound code as mentioned by RalfJung in https://github.com/rust-lang/rust/pull/85769#issuecomment-886491680:

> ... technically const-code could transmute/cast an int to a ptr and then transmute it back and that would be correct -- so the lint will deny some sound code. Does not seem terribly likely though.

move f16/f128 const fn under f16/f128 feature gate

The `*_const` features were added to work around https://github.com/rust-lang/rust/issues/129656, which should not be needed any more.

Make opaque types regular HIR nodes

Having opaque types as HIR owner introduces all sorts of complications. This PR proposes to make them regular HIR nodes instead.

I haven't gone through all the test changes yet, so there may be a few surprises.

Many thanks to `@camelid` for the first draft.

47b681d276 Rollup merge of #130518 - scottmcm:stabilize-controlflow-extra, r=dtolnay
Stabilize the `map`/`value` methods on `ControlFlow`

And fix the stability attribute on the `pub use` in `core::ops`.

libs-api in https://github.com/rust-lang/rust/issues/75744#issuecomment-2231214910 seemed reasonably happy with naming for these, so let's try for an FCP.

Summary:
```rust
impl<B, C> ControlFlow<B, C> {
    pub fn break_value(self) -> Option<B>;
    pub fn map_break<T>(self, f: impl FnOnce(B) -> T) -> ControlFlow<T, C>;
    pub fn continue_value(self) -> Option<C>;
    pub fn map_continue<T>(self, f: impl FnOnce(C) -> T) -> ControlFlow<B, T>;
}
```

Resolves #75744

``@rustbot`` label +needs-fcp +t-libs-api -t-libs

---

Aside, in case it keeps someone else from going down the same dead end: I looked at the `{break,continue}_value` methods and tried to make them `const` as part of this, but that's disallowed because of not having `const Drop`, so put it back to not even unstably-const.

Refactoring to `OpaqueTyOrigin`

Pulled out of a larger PR that uses these changes to do cross-crate encoding of opaque origin, so we can use them for edition 2024 migrations. These changes should be self-explanatory on their own, tho 😄

Clippy subtree update

r? `@Manishearth`

Really delayed sync (2 1/2 weeks), because of a `debug_assertion` we hit, and I didn't have the time to investigate earlier.

It would be nice to merge this PR with some priority, as it includes a lot of formatting changes due to the rustfmt bump.

Include Cargo.lock update due to Clippy version bump and ui_test bump in Clippy.

e691743119 Rollup merge of #130764 - compiler-errors:inherent, r=estebank
Separate collection of crate-local inherent impls from error tracking

#119895 changed the return type of the `crate_inherent_impls` query from `CrateInherentImpls` to `Result<CrateInherentImpls, ErrorGuaranteed>` to avoid needing to use the non-parallel-friendly `track_errors()` to track if an error was reporting from within the query... This was mostly fine until #121113, which stopped halting compilation when we hit an `Err(ErrorGuaranteed)` in the `crate_inherent_impls` query.

Thus we proceed onwards to typeck, and since a return type of `Result<CrateInherentImpls, ErrorGuaranteed>` means that the query can *either* return one of "the list inherent impls" or "error has been reported", later on when we want to assemble method or associated item candidates for inherent impls, we were just treating any `Err(ErrorGuaranteed)` return value as if Rust had no inherent impls defined anywhere at all! This leads to basically every inherent method call failing with an error, lol, which was reported in #127798.

This PR changes the `crate_inherent_impls` query to return `(CrateInherentImpls, Result<(), ErrorGuaranteed>)`, i.e. returning the inherent impls collected *and* whether an error was reported in the query itself. It firewalls the latter part of that query into a new `crate_inherent_impls_validity_check` just for the `ensure()` call.

This fixes #127798.
