5124: (Partially) fix handling of type params depending on type params r=matklad a=flodiebold
If the first type parameter gets inferred, that's still not handled correctly; it'll require some more refactoring: E.g. if we have `Thing<T, F=fn() -> T>` and then instantiate `Thing<_>`, that gets turned into `Thing<_, fn() -> _>` before the `_` is instantiated into a type variable -- so afterwards, we have two type variables without any connection to each other.

Move unsafe_expressions to unsafe_validation.rs, replace vec tracking of
child exprs with inline macro, add debug assert to ensure tracked
children match walked children exactly

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**:
```

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`.

When referring to an associated type of a super trait, we used the substs of the
subtrait. That led to the #4931 crash if the subtrait had less parameters, but
it could also lead to other incorrectness if just the order was different.
Fixes#4931.
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.
