RewrittenProto: use Int2RefMap

- RemovedArguments has now Int2Ref Map
  over a list of elements where each item
  has the index.
- RemovedArguments empty has now an empty map
  instead of null (1 extra instance), removed
  corresponding null checks
- Made sure empty RemovedArguments use the
  empty instance
- Fixed a bug where arg 0 of static method was
  never considered as unused.
