Summary

Same as for the previous PR. I assumed that I would need to match on all Expr and this isn't easily possible with AnyNodeRef.
That's why I introduced a new ExpressionRef which is the unowned pendant to Expr. There are a few cases where it allows me to remove some debug assertions, but I didn't end up using it heavily.

We can merge it if you find it useful, or leave it as is.

Test Plan

It compiles

Closing for now as it isn't needed right way. We can reconsider adding ExpressionRef when the need arises.

Introduce ExpressionRef (#6637)
1334232 
## Summary

This PR revives the `ExpressionRef` concept introduced in
#5644, motivated by the change we
want to make in #6575 to narrow
the type of the expression that can be passed to `parenthesized_range`.

## Test Plan

`cargo test`
