`VisitorMut` reaches aliases through `pre_visit_select` /
`post_visit_select`, added in #2235. They hand you `&mut Select`, whose
`projection` holds `SelectItem::ExprWithAlias { expr, alias }`, so the alias
can be renamed there. `pre_visit_ident` also visits every identifier, alias
names included, and ORDER BY clauses nested in subqueries are reachable through
`pre_visit_query` and `pre_visit_order_by`. Closing as answered, please reopen
if a node you need is still unreachable.
