```

It's as if we're returning `None` for a well-known trait that `chalk` asks about. That seems to happen for `Deref`, `CoerceUnsized` and `Try`.

4947: Replace `impls_in_trait` query with smarter use of `CrateImplDefs` r=matklad a=jonas-schievink

`impls_in_trait` was allocating a whopping ~400 MB of RAM when running analysis-stats on r-a itself.

Remove it, instead adding a query that computes a summary `CrateImplDefs` map for all transitive dependencies. This can probably still be made more efficient, but this already reduces the peak memory usage by 25% without much performance impact on analysis-stats.

**Before**:

```
Total: 34.962107188s, 2083mb allocated 2141mb resident
   422mb ImplsForTraitQuery (deps)
   250mb CrateDefMapQueryQuery
   147mb MacroArgQuery
   140mb TraitSolveQuery (deps)
    68mb InferQueryQuery (deps)
    62mb ImplDatumQuery (deps)
```

**After**:

```
Total: 35.261100358s, 1520mb allocated 1569mb resident
   250mb CrateDefMapQueryQuery
   147mb MacroArgQuery

4958: Infer FnSig via Fn traits r=flodiebold a=adamrk

Addresses https://github.com/rust-analyzer/rust-analyzer/issues/4481.
When inferring types check if the callee implements one of the builtin `Fn` traits. Also autoderef the callee before trying to figure out it's `FnSig`.

2745cb37c1 Use correct substs for super trait assoc types
When referring to an associated type of a super trait, we used the substs of the

it could also lead to other incorrectness if just the order was different.

4851: Add quickfix to add a struct field r=TimoFreiberg a=TimoFreiberg

Related to #4563 
I created a quickfix for record literals first because the NoSuchField diagnostic was already there.
To offer that quickfix for FieldExprs with unknown fields I'd need to add a new diagnostic (or create a `NoSuchField` diagnostic for those cases)

I think it'd make sense to make this a snippet completion (to select the generated type), but this would require changing the `Analysis` API and I'd like some feedback before I touch that.

4689: Implement return position impl trait / opaque type support r=matklad a=flodiebold

This is working, but I'm not that happy with how the lowering works. We might need an additional representation between `TypeRef` and `Ty` where names are resolved and `impl Trait` bounds are separated out, but things like inference variables don't exist and `impl Trait` is always represented the same way.

Also note that this doesn't implement correct handling of RPIT *inside* the function (which involves turning the `impl Trait`s into variables and creating obligations for them). That intermediate representation might help there as well.

Chalk newly added TypeName::Never and Array; I implemented the conversion for
Never, but not Array since that expects a const argument.

194dd9eb0d Use Chalk's Ty::Function for function pointer types
Function pointers can be 'higher-ranked' over lifetimes, which is why they're
not an application type in Chalk, but since we don't model lifetimes it doesn't
matter for us yet.

4497: Create LowerCtx on the fly r=matklad a=edwin0cheng

Previously we create `LowerCtx` at the beginning of lowering, however, the hygiene content is in fact changing between macro expression expanding. 

This PR change it to create the `LowerCtx` on the fly to fix above bug.

However, #4465 is not fixed by this PR, the goto-def is still not work yet. It only fixed the infer part.

811d25b723 Allow calling dyn trait super trait methods without the super trait in scope
This also removes some vestiges of the old impl trait support which I think
aren't currently in use.

3f42b2e837 Handle Self in values and patterns
I.e.
 - `Self(x)` or `Self` in tuple/unit struct impls
 - `Self::Variant(x)` or `Self::Variant` in enum impls
 - the same in patterns

Fixes #4454.
