fc6b7c8b38 Reformat for new mode syntax, step 1 
Long lines were fixed in a very crude way, as I'll be following up
with another reformat in a bit.

7bbe8d2e8c Stop relying on klunky hack in alias.rs 
It assumed node_ids increased monotonically for locals, but macros
make this no longer the case, and it was a dubious assumption anyway.
It now numbers locals itself and uses that to determine which precede
which.

7d08678b74 Implement pattern guards 
The syntax is

    alt x {
        mypat where mycond { ... }
    }

The condition may refer to any of the variables bound by the pattern.
When a guard fails, pattern-matching continues with the next pattern.

Closes #857

This changes the indexing syntax from .() to [], the vector syntax from ~[] to
[] and the extension syntax from #fmt() to #fmt[]

67e361a940 Introduce a ty_infer ast node and use it instead of option::t[ty]. 
This actually basically makes things worse, since we get less nice
type system guarentees but it will make doing type inferred blocks a
fair deal less painful. I'm not /really/ happy about this...

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.

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?

Multi-var-decls without the typestate extension

Add a loop

bd4aeef78b Beginnings of support for constrained types 
Programs with constrained types now parse and typecheck, but
typestate doesn't check them specially, so the one relevant test
case so far is XFAILed.

Also rewrote all of the constraint-related data structures in the
process (again), for some reason. I got rid of a superfluous
data structure in the context that was mapping front-end constraints
to resolved constraints, instead handling constraints in the same
way in which everything else gets resolved.

86ee3454a1 Implement or-patterns in case clauses 
You can now say

    expr_move(?dst, ?src) | expr_assign(?dst, ?src) { ... }

to match both expr_move and expr_assign. The names, types, and number
of bound names have to match in all the patterns.

Closes #449.
