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.

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.

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.
