Rather large commit to get coroutine cancellation working.
This includes what you would expect, like new code in exceptions and a new
test, but it also includes a bunch of other things.
New coroutine state, currently just marks that the stack was cancelled. New
helpers for checking code structure and generating vtables. Changes to the
coroutine interface so resume may throw exceptions on cancellation, plus the
exception type that is thrown. Changes to the coroutine keyword generation to
generate exception code for each type of coroutine.
