big global change, so let me explain in more detail. This refactoring CL does the following: - moves all the dart code for isolates in a common library (lib/isolate) - changes frog to understand 'dart:isolate' imoprts by loading the code from the location above. - changes the vm to undernstand 'dart:isolate' imports by creating a separate library that is part of the bootstrap. This follows the same code-structure that Todd suggested in his CL introducing the mirror library - changes dartc to use the shared isolate library as the source of truth for type checking. I left around some of the internal js code in dartc so that the backend continues to work for apps that don't use isolates. - changes all tests that use isolates to import the library explicitly (this is a large bulk of the files in this CL) - changes test status for tests we can't fix in this repo (e.g. co19) - splits the isolate library code to make it possible to preserve some tests without exposing internal types (e.g. tests about serialization/deserialization) - changes the create_sdk script to copy the isolate library to the sdk - includes the isolate library in dartdoc I'll wait for at least one lgtm from each area (dartc, vm, frog, sdk) There is one important pending thing this CL doesn't do: - update test_runner.dart: This should be updated next time we upload the new binaries to tool/testing/bin - dartium specific changes: Vijay, is there anything I need to do for dartium?
