fix: assists no longer break indentation
Fixes https://github.com/rust-lang/rust-analyzer/issues/14674
These are _ad hoc_ patches for a number of assists that can produce incorrectly indented code, namely:
- generate_derive
- add_missing_impl_members
- add_missing_default_members
Some general solution is required in future, as the same problem arises in many other assists, e.g.
- replace_derive_with...
- generate_default_from_enum...
- generate_default_from_new
- generate_delegate_methods
(the list is incomplete)
Fix: a TODO and some clippy fixes
- fix(todo): implement IntoIterator for ArenaMap<IDX, V>
- chore: remove unused method
- fix: remove useless `return`s
- fix: various clippy lints
- fix: simplify boolean test to a single negation
fix: introduce new type var when expectation for ref pat is not ref
Fixes#14840
When we infer the type of ref patterns, its expected type may not be reference type: 1) expected type is an unresolved inference variable, or 2) expected type is erroneously other kind of type. In either case, we should produce a reference type with a new type variable rather than an error type so that we can continue inferring the inner patterns without further errors because of the (possible) type mismatch of this pattern.
fix: consider all tokens in macro expr when analyzing locals
Fixes#14687
2 fixes for `extract_function` assist (related closely enough that I squashed into one commit):
- Locals in macro expressions have been analyzed only when they are in the top-level token tree the macro call wraps. We should consider all descendant tokens.
- `self` in macro expressions haven't been analyzed.
Fix `preorder_expr` skipping the `else` block of let-else statements
Fixes exit/yield points not getting highlighted in such blocks for `highlight_related` (#14813; and possibly other bugs in features that use `preorder_expr`).

Add layout info for enum variant and locals
The size of enum variant is what rustdoc shows (https://github.com/rust-lang/rust/pull/86263). I also added layout info for locals since it helps finding size of unnameable types like closures inside other structs or impl traits.
Add `moved-out-of-ref` diagnostic
This is marked as experimental, since spans are terrible, there are some false positives due #14754, and it doesn't play well with unknown types. But I hope we can soon lift it.
Partially support panic message in `MirEvalError`
And bring the metrics back, by using `::core` instead of `$crate` in `format_args!` (it looks like eager macros don't support them).
