5428a22b95 First cut at dtors for classes
Classes with dtors should compile now. Haven't yet tested
whether they actually run correctly.

Beginnings of support for #2295, though that won't be done until
there's more test cases and resources are removed.

4f105e4025 In resolve, visit the path in an iface ref
Necessary to resolve any type arguments in a ref to a parameterized
iface. This meant that, for example:

class A implements B<int> { ...

didn't work before, because the "int" in B's argument wasn't getting
visited, and thus wasn't getting resolved. Now it works.

Partially addresses Issue #2288, but I also want to check that class
ty params can appear as the type arguments to ifaces (for example,

class A<T> implements B<T> {...

should work.)

Niko Matsakis
1ba4ca4c4a allow fn exprs to omit arg types
also, avoid using type variables for fn args with omitted types
unless necessary.  This will be important for bound regions in
fn types.

164039e867 Don't re-export a glob-imported ID when the same ID is defined within
a module

See the test case I added (issue-2316-c) for a concrete example.
issue-2316 also contains the originally reported test case. resolve
was using bitwise or instead of logical or when checking exports,
resulting in excessively eager evaluation. A one-line fix that took
six hours to isolate ;-)

43751e45d9 rustc: Rename llalign_of_real to llalign_of_pref
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)

734166f41c Print out return type correctly in typestate error message
In the "not all paths return" error message, typestate was printing
the AST type from the fn decl, not the ty::t type. This ended in tears
when the AST return type was "ty_infer". Now it looks up the function node
ID's type and uses util::ppaux::ty_to_str instead.

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.)

5a3875e998 Print "expected a record with field..." fields in the right order
Because terr_record_mismatch was getting called by infer::flds,
which takes types a and b where it's trying to prove a <: b, the
expected and actual fields were switched. Fixed it. Closes #2094

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.

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.
