Merge #7557
7557: Intern `TypeRef`s in the containing `ItemTree` r=jonas-schievink a=jonas-schievink This reduces the memory used by `ItemTreeQuery` by ~20%. As it turns out, `TypeRef` is very heavy, and is used a lot in `ItemTree`: * Many types are frequently repeated throughout the same file. This is what this PR addresses by storing identical `TypeRef`s only once per `ItemTree`. * The vast majority of `TypeRef` consist of a plain path with only a single element. "Type anchors" like in `<Ty>::func` are used incredibly rarely, and even multi-segment paths are much rarer than single-segment paths. Co-authored-by: Jonas Schievink <[email protected]>
