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?

11663: Internal: Add hir_def::MacroId, add Macro{Id} to ModuleDef{Id} r=Veykril a=Veykril
With this we can now handle macros like we handle ModuleDefs making them work more like other definitions and allowing us to remove a bunch of special cases. This also enables us to track the modules these macros are defined in, instead of only recording the crate they come from.
Introduces a new class of `MacroId`s (for each of the 3 macro kinds) into `hir_def`. We can't reuse `MacroDefId` as that is defined in `hir_expand` which doesn't know of modules, so now we have two different macro ids, this unfortunately requires some back and forth mapping between the two via database accesses which I hope won't be too expensive.

11623: fix: Add type variable table to InferenceTableSnapshot r=flodiebold a=tysg
Fixes#11601.
I observed that removing the `rollback` line in 6fc3d3aa4c fixes the issue.
Looking at the stacktrace, I believe not restoring `type_variable_table` causes `type_variable_table` and `var_unification_table` to go out of sync, then when `hir_ty::infer::unify::InferenceTable::new_var` tries to extend `type_variable_table` to be the same length as `var_unification_table`, problems will arise.
However, I cannot pinpoint exactly how or where the vector capacity overflow happens, so my understanding might not be correct after all.
