152cbaade7 Move functions from syntax::ast to syntax::ast_util
This leaves syntax::ast just defining the AST, which strikes me as somewhat
nicer

1c786bcc82 Initialize all constraints to False
Previously, typestate was initializing the init constraint for
a declared-but-not-initialized variable (like x in "let x;") to False,
but other constraints to Don't-know. This led to over-lenient results
when a variable was used before declaration (see the included test
case). Now, everything gets initialized to False in the prestate/poststate-
finding phase, and Don't-know should only be used in pre/postconditions.

This aspect of the algorithm really needs formalization (just on paper),
but for now, this closes #700

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.

9ca0ce91bf Initial implementation of typestate for closures.
There are still things not handled properly: relying on other preconditions
of upvars is likely to cause bad things to happen. We probably want to
disallow it.

add an equivalent to visit.rs later.
