* Move each section of the original file into a new test file.
* Remove the use of multi-tests entirely to avoid running ~90% of these
tests 5 times each.
* async_star2_test/02 became cancel_while_paused_at_yield_test.dart. I will
approve the existing failures of this newly named test.
* All other sections marked as multi-tests actually appear to be passing on
all configurations so they didn't need to be broken out.
* Cleanup now unnecessary lines in the status file.
