Fixes to mock SDK to enable dart:core to be summarized.

This CL makes the following changes to the mock SDK used by
AnalysisContextFactory.initContextWithCore:

- Getters created by the ElementFactory have their `synthetic`
  property set correctly, and their corresponding synthetic fields
  have their `final` property set correctly.

- The following class elements all have at least one constructor:
  Function, Iterable, Iterator, Map, Null, StackTrace, Type, num,
  double, _Proxy.

This allows resynthesize_test.dart's `test_core` to pass.

Also, some minor improvements are made to resynthesize_test.dart to
allow failures to be diagnosed more easily.
