  1. Do not reorder assignments when unaliasing symbols 

    Use collector `toImmutableMap` instead of `Collectors.toMap`
to avoid shuffling the collected assignments.
This change restores the state that the visitor methods
don't reorder outputs of ProjectNode and ApplyNode,
which changed when a check for duplicate assignments was added.
