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.

4be7e1e5cd Pass all arguments by reference, make immut alias mode equiv to value
Arguments that can't be safely referenced will be implicitly copied.

(Warnings for expensive copies will be forthcoming.)

This will allow us to get rid of most of the ampersands in function
signatures. See [1].

fb196e6ef1 Make alias analysis properly recognize closures in call position
I figured this'd break a few things, but in fact it causes no problems
whatsoever.

6ba4eacddf Make resolve recognize upvars
Upvars are now marked with def_upvar throughout, not just when going
through freevars::lookup_def. This makes things less error-prone. One
thing to watch out for is that def_upvar is used in `for each` bodies
too, when they refer to a local outside the body.

2d1dec78e7 Move mutability checking into its own pass.
Having it in the alias pass was slightly more efficient (finding
expression roots has to be done in both passes), but further muddled
up the already complex alias checker.

Also factors out some duplication in the mutability-checking code.

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.

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

b24f978011 Drop arguments on the caller side, not the callee
This makes it easier for the caller to optimize the take/drop away for
temporary values, and opens up new possibilities for alias handling.

Breaks tail calls.

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
