c31472e845 Refactor the typeck::writeback AST walk 
All visitors take a wb_ctxt now instead of some taking a fn_ctxt and some
taking an ignore flag.

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.

f279e0d76e Handle pattern-bound upvars 
If a closure inside a case alternative (for example, a for each loop)
referenced a pattern-bound variable, this would cause an assertion
failure in trans. Changed trans::collect_upvars to handle pattern-bound
vars correctly.

Incidentally, eliminated all direct uses of option::get in trans.

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.

a9d84ab28a Make type unification failures non-fatal 
Add a failure checkpoint after the typechecking pass. There are still many
fatal errors in typeck, but loosening up this one makes it easier to lean on
the compiler when making changes to types.

Issue #440.

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.

04acba7968 Move pretty-printing 'modes' into a callback hook 
This way, the pretty-printer does not have to know about middle::ty.

(This is a preparation for separating the AST functionality into a
separate crate.)
