So far pathTo(span) would only guarantee to return the path to the closest tree enclosing `span` if trees were non-overlapping. This is property does not hold for typed trees, yet `pathTo` is called from `Interactive` on such typed trees. This commit makes `pathTo` work correctly also for overlapping trees.
With given coming last, some of the no-overlaps and in-order position checks have to be weakened. But with the more generalized pathTo implementation, non-overlapping and in-order is not really needed anymore.
They printed as normal arguments before.
The previous syntax was unparseable without major contortions in the Parser.

These were printed as old-style implicit parameters before. This is in preparation for merging it with `Implied`. We already compensate for it when printing modifiers by eliding it when it appear with `Param`.
Synthesized creator expressions for classes passed all parameters as normal arguments. This works no longer with `given` clauses. We have use `given` arguments for those.
