According to the language specification:
1) When 'break' is executed in the 'await for' loop (in 'main'),
the underlying stream subscription is canceled.
2) When async* function ('consume') has stopped at 'yield' or 'yield*',
and the stream is canceled, the 'yield' / 'yield*' statement returns
without an object. It also means that code in 'consume()' after
the loop is not executed and it doesn't append ")" to the log.
So the test expectations are fixed to avoid expecting trailing ")"
at the log when there is a 'break' out of the 'await for' loop.

Previously there was a window between the decision to resume generator
and actually running the micro-task. The stream could be canceled
during that window, making running the generator incorrect.
The solution is to check if the stream was canceled right before
resuming the generator in yield/yield*.
This change also unifies yield and yield* to check if the stream
was canceled even before suspending the generator.

And also copies over and renames all of the status files in those
directories.
Then it migrates those tests to be static error free in NNBD.
Finally, adds support to the test_runner for the new suites.
Note that this review is split into multiple patchsets. The first
patchset is a straight copy of the existing files. Then the later
patchsets have the interesting changes.
