5c12cd72f4 Allow classes to implement ifaces
Introduce syntax like:

iface animal { ... }
class cat implements animal { ... }

to allow classes to implement ifaces. Casting classes to ifaces
is *not* yet supported. ifaces that a class implements are not
yet included in metadata.

The syntax is subject to change, and may go away completely if we
decide to use duck typing to relate classes with ifaces (see
http://smallcultfollowing.com/babysteps/blog/2012/04/10/declared-vs-duckish-typing/ )

c902eafa14 Convert old-style for loops to new-style
Most could use the each method, but because of the hack used to
disambiguate old- and new-style loops, some had to use vec::each.

(This hack will go away soon.)

c0d61795de wip: refactor repr of regions
- we now distinguish bound/free parameters (see region-param
  test case for why this is necessary)
- we also track bounds on region variables
- also, restructure fold_ty() to have multiple variants without
  duplication instead of one overloaded folder.  This also allows
  for using block functions.

c7082ce8e8 Require "self" as base expression for intra-class method or field references
All field or method references within a class must begin with "self." now.
A bare reference to a field or method in the same class will no longer
typecheck.

f7bbe537c1 Allow explicit self-calls within classes
Allow writing self.f() within a class that has a method f. In a future
commit, this syntax will be required. For now, you can write either
self.f() or f().

I added a "privacy" field to all methods (whether class methods or not),
which allowed me to refactor the AST somewhat (getting rid of the
class_item type; now there's just class_member).

edb747ceed Enforce mutability declarations in classes; correct shapes for classes
1. Enforce mutability declarations on class fields. Don't allow any
mutation of class fields not declared as mutable (except inside the
constructor).

2. Handle classes correctly in shape (treat classes like records).

11610f9ca1 In typeck, don't call ty::store_iface_methods on private methods
This was resulting in a different error message depending on whether
the private method you were trying to call was in the same crate
or a different one.
