that doesn't look like a simplification---it's hard to trace global state.

Dart interface renames naturally belong to type registry. Hiding renames in
IDLTypeInfo.dart_type() greatly simplifies dart code generation in dart:html.

I do agree w/ it.  But I hate this temporary set renames field on the class (aka
global state).

I think we'd better thread this thing around.
