[analyzer] Optimize UsedLocalElements.merge().

See b/235079681 (analyzer is slow with many part file).

1. Pre-compute UsedLocalElements.merge() before calling '_computeHints()' on each part files.
2. Optimize HashSet insertion:
   Remove implementation of ParameterMember.hashCode.
   This implementation was not linked to a corresponding '.==' override.
   So, while not wrong, it did cause many collisions not resulting in equality.
