- `T: ~const Drop` has a special meaning in Rust 1.61 that we don't implement.
(So ideally, we'd only ignore `~const Drop`, but this should be fine
for now.)
- `Destruct` impls are built-in in 1.62 (current nightlies as of 08-04-2022), so until
the builtin impls are supported by Chalk, we ignore them as well.
Since `Destruct` is implemented for everything in non-const contexts
IIUC, this should also work fine.
Fixes#11932.
11920: Consider types of const generics r=flodiebold a=HKalbasi
fix#11913
We should emit type_mismatch in const generics, probably after #7434. Currently they will lead to a misleading, time of use type error (like the added test).

11840: Fix another const generic panic r=flodiebold a=HKalbasi
fix#11835
If I change `dyn` to `impl` in the test, it will infer the type as `IntoIterator::Item<impl Iterator<Item = [Ar<u8, 7>; 9]> + ?Sized>` instead of `[Ar<u8, 7>; 9]`. Maybe it needs some action?

In code like this:
```rust
impl<T> Option<T> {
fn as_deref(&self) -> T::Target where T: Deref {}
}
```
when trying to resolve the associated type `T::Target`, we were only
looking at the bounds on the impl (where the type parameter is defined),
but the method can add additional bounds that can also be used to refer
to associated types. Hence, when resolving such an associated type, it's
not enough to just know the type parameter T, we also need to know
exactly where we are currently.
This fixes#11364 (beta apparently switched some bounds around).
10440: Fix Clippy warnings and replace some `if let`s with `match` r=Veykril a=arzg
I decided to try fixing a bunch of Clippy warnings. I am aware of this project’s opinion of Clippy (I have read both [rust-lang/clippy#5537](https://github.com/rust-lang/rust-clippy/issues/5537) and [rust-analyzer/rowan#57 (comment)](https://github.com/rust-analyzer/rowan/pull/57#discussion_r415676159)), so I totally understand if part of or the entirety of this PR is rejected. In particular, I can see how the semicolons and `if let` vs `match` commits provide comparatively little benefit when compared to the ensuing churn.
I tried to separate each kind of change into its own commit to make it easier to discard certain changes. I also only applied Clippy suggestions where I thought they provided a definite improvement to the code (apart from semicolons, which is IMO more of a formatting/consistency question than a linting question). In the end I accumulated a list of 28 Clippy lints I ignored entirely.
Sidenote: I should really have asked about this on Zulip before going through all 1,555 `if let`s in the codebase to decide which ones definitely look better as `match` :P

... instead of using `AliasTy`. Chalk turns the alias type into the
placeholder during unification anyway, which confuses our method
resolution logic.
Fixes#9530.
9260: tree-wide: make rustdoc links spiky so they are clickable r=matklad a=lf-
Rustdoc was complaining about these while I was running with --document-private-items and I figure they should be fixed.
