Try to use the JS helper from somewhere in the HTML library.

File lib/compiler/implementation/native_handler.dart (right):

https://chromiumcodereview.appspot.com/10694082/diff/1/lib/compiler/implement...
lib/compiler/implementation/native_handler.dart:84:
library.define(compiler.findHelper(const SourceString('JS')), compiler);
Maybe we should extend the map in library_map.dart to a proper central "dart

It seems better than having per-library information smattered all over the code
base.
