c047cfb710 Unwind the stack on task failure 
When a task fails, we will throw an exception, then catch it at the bottom of
the stack.

On Windows we don't do this yet because the exception doesn't propagate
correctly.

No cleanups yet.

Issue #236

c337fd5467 Child tasks take a ref to their parents 
This is so that when a child dies after the parent, it still holds a valid
pointer and can call supervisor->kill() safely.

25ae3d655c Rewrite spawn yet again 
The motivation here is that the bottom of each stack needs to contain a C++
try/catch block so that we can unwind. This is already the case for main, but
not spawned tasks.

b5f9053423 Add a constraint to trans::type_of 
trans::type_of now has a constraint saying that its type argument
is statically sized. This eliminates the "impossible happened" case
in type_of. Yay!

I note that this change decreased translation time for stage2/rustc
from 16.1 s to 14.0 s. I also think many of the remaining checks
could be eliminated with some mildly clever use of constrained types
and further preconditions. Future work!

there's no else branch. (Oops!)

Experimenting with adding typestate constraints in the compiler.
Added a constraint to GEP_tag that says the variant index is in
