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

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.

5e1a6dac44 Parse nullary ret correctly 
ret is similar to fail: if not followed by an expression, it

fail if ret was followed by a close paren (for example). Fixed it.

73e6a4f9e5 Elide existing main function when building a test runner. Issue #428 
This prevents any defined main function from colliding with the one
synthesized for the test runner. This is not the best solution since it
doesn't compile a function the user defined, but I don't think it's likely to
be a problem in the near term.

8e585e7008 Support paren-free and lightweight-case syntax 
(The old syntax is still supported as well, for now.)

It is now possible to leave out the parens around if, while, and
do/while conditions, and around alt expressions. Cases in an alt block
can now leave off the case keyword and parens around the pattern.

After the next snapshot, we can start migrating our code to use the
new alt syntax, probably with a pretty-printer pass. The paren-free
syntax will remain optional (you may always parenthesize expressions),
but the old case syntax will no longer be supported in the future.

(Possible now that a snapshot took place.)

2cb129355b Change ast::meta_name_value to accept any literal, not just string 
This isn't useful for much of anything yet, since metadata::encoder doesn't
know how to handle the non-string variants.

6fd6fdea93 Move everything syntax-related to syntax/, break deps on rest of compiler 
src/comp/syntax is currently just a sub-module of rustc, but it will,
in the near future, be its own crate. This includes:

 - The AST data structure
 - The parser
 - The pretty-printer
 - Visit, walk, and fold
 - The syntax extension system
 - Some utility stuff that should be in the stdlib*

*) Stdlib extensions currently require a snapshot before they can be
   used, and the win build is very broken right now. This is temporary
   and will be cleaned up when one of those problems goes away.

A lot of code was moved by this patch, mostly towards a more organized
layout. Some package paths did get longer, and I guess the new layout
will take some getting used to. Sorry about that!

Please try not to re-introduce any dependencies in syntax/ on any of
the other src/comp/ subdirs.
