…safe_op_in_unsafe_fn

Co-authored-by: Léo Lanteri Thauvin <[email protected]>

Module is completed because it doesn’t have any diagnostics

…-drop-is-bad, r=TaKO8Ki Do not allow `Drop` impl on foreign fundamental types `Drop` should not be implemented on `Pin<T>` even if `T` is local. This does not trigger regular orphan rules is because `Pin` is `#[fundamental]`... but we don't allow specialized `Drop` impls anyways, so these rules are not sufficient to prevent this impl on stable. Let's just choose even stricter rules, since we shouldn't be implementing `Drop` on a foreign ADT ever. Fixes rust-lang#99575

…n, r=jackh726 never consider unsafe blocks unused if they would be required with deny(unsafe_op_in_unsafe_fn) Judging from rust-lang#71668 (comment) the consensus nowadays seems to be that we should never consider an unsafe block unused if it was required with `deny(unsafe_op_in_unsafe_fn)`, no matter whether that lint is actually enabled or not. So let's adjust rustc accordingly. The first commit does the change, the 2nd does some cleanup.

…enkov make NOP dyn casts not require anything about the vtable As suggested [on Zulip](https://rust-lang.zulipchat.com/#narrow/stream/144729-t-types/topic/dyn-upcasting.20stabilization/near/292151439). This matches what the codegen backends already do, and what Miri did do until rust-lang#99420 when I made it super extra paranoid.

Cleanup rustdoc themes This PR continues our work to simplify the rustdoc themes by relying more on CSS variables. Interestingly enough, this time it allowed me to realize that we were having a lot of different colors for borders even though the difference is unnoticeable. I used this opportunity to unify them. The live demo is [here](https://rustdoc.crud.net/imperio/cleanup-themes/std/index.html). r? `@jsha`

…ion, r=tmiasko Only check the `DefId` for the recursion check in MIR inliner. The current history check compares `Instance`s, so it cannot detect cases of polymorphic recursion where `Substs` change. This PR makes it so we only compare `DefId`s, ignoring any change in `Substs`. According to rust-lang#100522 (comment), in practice only very few inlining decisions change. Fixes rust-lang#100476

Manually implement Debug for ImportKind. This avoids crashing due to an infinite loop when running with `RUSTC_LOG=rustc_resolve`.

Don't fix builtin index when Where clause is found Where clause shadows blanket impl for `Index` which causes normalization to not occur, which causes ICE to happen when we typeck. r? `@compiler-errors` Fixes rust-lang#91633

…pe-ir, r=compiler-errors Add diagnostics lints to `rustc_type_ir` module Module is complete. It doesn’t have any diagnostics.

…1, r=jsha rustdoc: count deref and non-deref as same set of used methods Fixes rust-lang#100679
