Properly process dart:core classes if dart:core is imported with prefix.

Properly process dart:core classes if dart:core is imported with prefix.

In this case we force prefix omission.  However, there is a twist: when
visit prefix.name form in send visitor later, we cannot tell it from
dynamic invocation and hence to play safe we add platform libs class name
to the set of forbidden names.

Also, most probably we need a proper support for top-level from dart:core.
