2d5b651f49 Assign collection element ty to loop local tvar when checking loops 
This makes the type declarationg for the loop variable optional in
most cases.

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.

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.

d1298f768c Have bind support non-alias parametric non-bound arguments. 
This was previously disallowed by the typechecker and not properly handled
in trans. I removed the typechecker check (replacing it with a simpler
check that spawned functions don't have type params) and fixed trans.

b9b674abe7 Start adding support for multiple variable declarations per stmt 
This adds parser support and most of the machinery for

    auto x = 10, y = 20;

However, the above still goes wrong somewhere in typestate, causing
the state checker to believe only the last variable in the list is
initialized after the statement.

Tim, if you have a moment, could you go over the changes to the tstate
code in this patch and see where I'm going wrong?

I was going to have to start pulling glue generation, which really
should go into a trans_glue file.
