ebde93861f Allow classes with dtors to be used before declaration 
get_item_val could generate an internal compiler error if a class with
a dtor was used before the class itself got translated, because it was
assuming that the dtor's node ID was always in the item_symbols table. Fixed
it to create a new symbol if necessary, and use it subsequently.

3f6e6532ac make vec fns/methods take imm slices. 
this also repairs the unsoundness in typing of unpack_slice,
which was silently converting a const ptr to an imm one.

ccc7651b48 In reachability, don't ignore nested items 
Reachability was considering nested items to be unreachable, which
was causing the bug in #2383. Once I fixed that, I also had to make
impl::make_impl_vtable instantiate methods where necessary, before
calling monomorphic_fn.

Closes #2383

34b42eeb65 change list so that it must be used in a purely boxed fashion 
The old way was inconsistent---the head was unboxed but the
tail was boxed.  This resulted in numerous needless copies and
also made the borrow check unhappy, because the head tended to be
stored in mutable memory.

This alignment is the "preferred" alignment of a type, which is not
necessarily the alignment the compiler will use when packing the
type into structures - that is the "ABI" alignment (in LLVM terms).

On x86, 64-bit ints have 8-byte preferred alignment, but 4-byte
ABI alignment.

825fd1808e lots of work to make iface/impls parameterized by regions 
- paths can now take region parameters, replacing the dirty hack
  I was doing before of abusing vstores.  vstores are now a bit
  of a hack though.

- fix various small bugs:
  - we never checked that iface types were compatible when casting
    to an iface with `as`
  - we allowed nonsense like int<int>
  - and more! (actually that may be it)

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.

4871f11439 std: change timeval to ns resolution timespec

7aae7320db std: change time::timeval to be {sec: i64, usec: i32}. 
It's possible to have negative times if expressing time before 1970, so
we should use signed types. Other platforms can return times at a higher
resolution, so we should use 64 bits.

1f892dcb01 Monomorphize class constructors, support generic classes and class methods 
Allow class methods to have type parameters (this is a change from the
original classes proposal).

Add test cases for classes with type parameters, and classes with methods
that have their own type parameters.

21be1379d5 Rename some core::option functions

I know these names are kind of ridiculous, but it's the best I could think of.
Feel free to bikeshed. Closes #2081

A bare reference to a field or method in the same class will no longer

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).

1. Enforce mutability declarations on class fields. Don't allow any
mutation of class fields not declared as mutable (except inside the
constructor).
