6c9b90d06a Be a little more clever about picking columns to match on in trans_alt 
This should result in slightly more efficient matching of 'complex'
patterns with multiple discriminants in them.

f8fa574864 Copy locals created by destructuring on the content of a box 
This is required so that assigning to these locals doesn't clobber
the content of the box.

(A possible optimization would be to only do this copying for
locals that actually are assigned to.)

5cf5f5024d Handle bang functions correctly in typestate 
The logic for how the "returns" constraint was handled was always
dodgy, for reasons explained in the comments I added to
auxiliary::fn_info in this commit. Fixed it by adding distinct
"returns" and "diverges" constraints for each function, which
are both handled positively (that is: for a ! function, the
"diverges" constraint must be true on every exit path; for
any other function, the "returns" constraint must be true
on every exit path).

Closes #779

985c32ef4c Partially implement destructuring locals 
You can now say

    let {bcx, val} = some_result_returner();

Similar for loop variables. Assigning to such variables is not safe
yet. Function arguments also remain a TODO.

ec46f07e6e Add a task spawning benchmark 
This is the kind of workload that the test runner generates - lots of tiny
little tasks - and currently it leaves the CPU underutilized.

6657e729de Lock the new task's scheduler when creating a task 
Previously we were locking the spawning task's scheduler. I couldn't
see that that was protecting anything. The newborn_task list in the new task's
scheduler though was unprotected from concurrent access. So now we're locking
the new task's scheduler.

96a629d2fa Base test concurrency on the number of scheduler threads. 
Ideally we would just spawn every test and collect the results but I'm not
entirely comfortable doing that yet for reasons that I'm too tired to remember
right now. Urgh.

6ba4e34959 Reduced test case for current backwarding bug. 
Still working on getting backwarding to play nicely with self and
overriding.  Currently can't fix issue #702 without breaking how self
and overriding interact.

126cd44c38 Refactor typestate code involving stmt_decls 
To handle multiple-LHS declarations with initializers properly,
I changed seq_states to take a list of expressions paired with optional
names, not just a list of expressions. Then, the same logic that handles
ordered lists of subexpressions everywhere else can handle multi-
declarations.
