The new feature 'declaring constructors' will change the syntax such
that it is an error for a non-declaring formal parameter declaration
to have the modifier `final`, and it is an error to use `var` as a
replacement for a type annotation (but the type annotation can still
be omitted entirely). This CL removes those modifiers such that the
tests will not start failing on things that aren't errors any more.
