fix typos

This target is a Tier 3 target so it's not tested on CI, and it's broken since last used so this commit fixes a small unwind-related issue that cropped up in the meantime.

Current `transform_ty` attempts to avoid cycles when normalizing `#[repr(transparent)]` types to their interior, but runs afoul of this pattern used in `self_cell`: ``` struct X<T> { x: u8, p: PhantomData<T>, } #[repr(transparent)] struct Y(X<Y>); ``` When attempting to normalize Y, it will still cycle indefinitely. By using a types-visited list, this will instead get expanded exactly one layer deep to X<Y>, and then stop, not attempting to normalize `Y` any further.

We already use `Instance` at declaration sites when available to glean additional information about possible abstractions of the type in use. This does the same when possible at callsites as well. The primary purpose of this change is to allow CFI to alter how it generates type information for indirect calls through `Virtual` instances.

Additional trait bounds beyond the principal trait and its implications are not possible in the vtable. This means that if a receiver is `&dyn Foo + Send`, the function will only be expecting `&dyn Foo`. This strips those auto traits off before CFI encoding.

…spans. This makes `-Zprint-type-sizes`'s output easier to read, because the name of an `async fn` is more immediately recognizable than its span. I also deleted the comment "FIXME(eddyb) should use `def_span`." because it appears to have already been fixed by commit 67727aa.

Rather than `.into_iter().rev().find_position(...)`, this case can simply call `.iter().rposition(...)`.

…onur-ozkan Introduce infrastructure for generating target docs See rust-lang#120745 It's highly unlikely that the format is optimal, but it's okay at least and can always be improved. Mostly posting this to get something working so we can continue. Use `TARGET_CHECK_ONLY=0` to actually build the book instead of just checking the new docs. r? `@davidtwco`

…, r=workingjubilee CFI: Support self_cell-like recursion Current `transform_ty` attempts to avoid cycles when normalizing `#[repr(transparent)]` types to their interior, but runs afoul of this pattern used in `self_cell`: ``` struct X<T> { x: u8, p: PhantomData<T>, } #[repr(transparent)] struct Y(X<Y>); ``` When attempting to normalize Y, it will still cycle indefinitely. By using a types-visited list, this will instead get expanded exactly one layer deep to X<Y>, and then stop, not attempting to normalize `Y` any further. This PR was split off from rust-lang#121962 as part of fixing the larger vtable compatibility issues. r? `````@workingjubilee`````

…ngjubilee CFI: Strip auto traits off Virtual calls We already use `Instance` at declaration sites when available to glean additional information about possible abstractions of the type in use. This does the same when possible at callsites as well. The primary purpose of this change is to allow CFI to alter how it generates type information for indirect calls through `Virtual` instances. This is needed for the "separate machinery" version of my approach to the vtable issues (rust-lang#122573), because we need to respond differently to a `Virtual` call to the same type as a non-virtual call, specifically [stripping auto traits off the receiver's `Self`](rust-lang@54b15b0) because there isn't a separate vtable for `Foo` vs `Foo + Send`. This would also make a more general underlying mechanism that could be used by rcvalle's [proposed drop detection / encoding](rust-lang@edcd1e2) if we end up using his approach, as we could condition out on the `def_id` in the CFI code rather than requiring the generating code to explicitly note whether it was calling drop.

…-errors In `pretty_print_type()`, print `async fn` futures' paths instead of spans. This makes `-Zprint-type-sizes`'s output easier to read, because the name of an `async fn` is more immediately recognizable than its span. This change will also synergize with my other `-Zprint-type-sizes` PR rust-lang#122922 which prints the type of child futures being awaited. I also deleted the comment "FIXME(eddyb) should use `def_span`." because it appears to have already been fixed by commit 67727aa.
