Split Nullarify functionality to ElimByName, Erasure

New phase ElimByName elimintaes by-name parameters. All other
occurrences of parameterless methods and ExprTypes are eliminated
in erasure.

The reason for the split like this is that it is very hard for
Nullarify to determine when to insert ()'s. The logic for this
is fragile because we need to look at previous denotations which might
not exist (before splitter) or might result from a merge
between parameterless and nullary methods. In Erasure
the same is much simpler to achieve.
