0334faef1f Improve pretty-printing of constraints 
(Methods still don't seem to have constraints associated with them.
Method types do, so I guess this is a TODO.)

252b8ffe42 Add support for new-style local decls 
let x = 5;
    let y: int = 10;
    // as soon as a typestate bug is fixed:
    let x: str = foo, y <- 20u;

'auto' and 'type-first let' will soon be dropped.

The old syntax is also still supported.

f0be65cb50 Fix span information returned by parser::parse_seq

properly reports the end of the closing token.

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
