Review Comment:
Good point, I looked and was able to switch `PipeExpression` from
`RuntimeReplaceable` to `Unevaluable` instead. Now `ResolveAliases` maintains
full responsibility for checking the invariants and removing the
`PipeExpression` once its child is resolved. I also synced from master and
updated the golden files.
