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.

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.

1262df652f Reduce the amount of locking in the kernel's memory region 
The only thing here that really needs locking on malloc and free is
access to the allocation list, which is only used for TRACK_ALLOCATIONS.

Improves bench/task-perf-vector-party by 70%.

c9c5ee252a Implement non-internal ivecs 
Vectors are now similar to our old, pre-internal vectors, except that
they are uniquely owned, not refcounted.

Their name should probably change too, then. I've renamed them to vec
in the runtime, will do so throughout the compiler later.

e58c48bdda Optimize += [x] into a simple push operation 
This is a preparation for making vectors always-on-the-heap again,
which would cause way too much malloc traffic for this idiom. I will
add an efficient std::vec::push in the future, and migrate += [x] to
that instead.

Reduces compiler code size by 3%

35c962e9a1 Pass structural types by pointer, not by value 
If we lose tail calls, this is possible. It simplifies things a lot.

Direct motivation: We want ivecs with pointers pointing into
themselves. When copying those, the pointers have to be adjusted. It
is impossible to this when copying them with Load/Store.

0a8bffceb3 Simplify the _rust_main/rust_start interface 
rust_start will always call _rust_main with the command line args, and it is
_rust_main's responsibility to free the args ivec heap. _rust_main will be
generated slightly differently depending on whether main takes an ivec or not:
if so then it's just passed through to main, otherwise it frees the ivec
directly.
