11842: Fix duplicate type mismatches with blocks r=flodiebold a=flodiebold
E.g. when there's a type mismatch on the return value of a function. To fix this, we have to return the expected type as the type of the block when there's a mismatch. That meant some IDE code that expected otherwise had to be adapted, in particular the "add return type" assist. For the "wrap in Ok/Some" quickfix, this sadly means it usually can't be applied in all branches of an if expression at the same time anymore, because there's a type mismatch for each branch that has the wrong type.

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?

11833: internal: Move mismatched arg count diagnostic to inference r=flodiebold a=flodiebold
This means we only need to handle legacy const generics in one place, and it fits there especially since there will be more diagnostics coming.

11831: fix: Disable ref_match for qualified paths as well r=flodiebold a=flodiebold
I.e. don't suggest `Foo::&foo()`.

11809: feat: disable experimental diagnostics by default r=jonas-schievink a=jonas-schievink
Now that we diagnose type mismatches, we have another diagnostic that can potentially produce false positives, so let's disable experimental diagnostics by default.

11810: internal: rename the 1.47 proc macro ABI to 1.48 r=jonas-schievink a=jonas-schievink
Closes https://github.com/rust-analyzer/rust-analyzer/issues/9898.
We don't support 1.47, so rename it to reflect that.

11772: Support constants in const eval r=HKalbasi a=HKalbasi
This PR enables evaluating things like this:
```rust
const X: usize = 2;
const Y: usize = 3 + X; // = 5
```
My target was nalgebra's `U5`, `U22`, ... which are defined as `type U5 = Const<{ SomeType5::SOME_ASSOC_CONST }>` but I didn't find out how to find the `ConstId` of the implementation of the trait, not the trait itself (possibly related to #4558 ? We can find associated type alias, so maybe this is doable already) So it doesn't help for nalgebra currently, but it is useful anyway.

Helps with the rocket 0.4 macros, at least on some Rust versions.

11801: fix: avoid returning `None` from `Span::join` to fix some proc macros r=jonas-schievink a=jonas-schievink
Some proc macros, notably rocket, `.unwrap()` the result of `Span::join` (and correctly so, it should never be `None`). We don't have a proper implementation of that API, so we always returned `None`. This changes our stub impl to return the first span instead.
Does not fully fix rocket's macros, they need other stuff to work too.
