coroutine support

[Lukas Stadler]

Ah, yes... I forgot to mention: it's currently only implemented in C1, 
and it doesn't even compile on C2 because I had to extend the compiler 
interface. But I'll probably get rid of that, and then it will be a lot 
easier to get C2 working as well.

You're of course right about the graceful shutdown - I will do that as 
well. And if at runtime you're getting crashes in weird places: chances 
are that -Xcomp will fix it.
