bors 0699d99516 Auto merge of #114115 - nnethercote:less-token-tree-cloning, r=petrochenkov
Less `TokenTree` cloning

`TokenTreeCursor` has this comment on it:
```
// FIXME: Many uses of this can be replaced with by-reference iterator to avoid clones.
```
This PR completes that FIXME. It doesn't have much perf effect, but at least we now know that.
