01740acd5a Initial implementation of enum discrimnant sizing.
Allows an enum with a discriminant to use any of the primitive integer
types to store it.  By default the smallest usable type is chosen, but
this can be overridden with an attribute: `#[repr(int)]` etc., or
`#[repr(C)]` to match the target's C ABI for the equivalent C enum.

This commit breaks a few things, due to transmutes that now no longer
match in size, or u8 enums being passed to C that expects int, or
reflection; later commits on this branch fix them.

0ac7a219f0 Updated std::Option, std::Either and std::Result
- Made naming schemes consistent between Option, Result and Either
- Changed Options Add implementation to work like the maybe monad (return None if any of the inputs is None)
- Removed duplicate Option::get and renamed all related functions to use the term `unwrap` instead

1c3dc294ce Allow uint discriminants and store them as such
Infers type of constants used as discriminants and ensures they are
integral, instead of forcing them to be a signed integer.

Also, stores discriminant values as uint instead of int interally and
deals with related fallout.

Fixes issue #7994

d2e9912aea vec: remove BaseIter implementation
I removed the `static-method-test.rs` test because it was heavily based
on `BaseIter` and there are plenty of other more complex uses of static
methods anyway.

49c74524e2 vec: rm old_iter implementations, except BaseIter
The removed test for issue #2611 is well covered by the `std::iterator`
module itself.

This adds the `count` method to `IteratorUtil` to replace `EqIter`.

f74e1935aa auto merge of #7123 : huonw/rust/more-str, r=thestinger
Moves all the remaining functions that could reasonably be methods to be methods, except for some FFI ones (which I believe @erickt is working on, possibly) and `each_split_within`, since I'm not really sure the details of it (I believe @kimundi wrote the current implementation, so maybe he could convert it to an external iterator method on `StrSlice`, e.g. `word_wrap_iter(&self) -> WordWrapIterator<'self>`, where `WordWrapIterator` impls `Iterator<&'self str>`. It probably won't be too hard, since it's already a state machine.)

This also cleans up the comparison impls for the string types, except I'm not sure how the lang items `eq_str` and `eq_str_uniq` need to be handled, so they (`eq_slice` and `eq`) remain stand-alone functions.

cc908b772c Remove @-fields from CrateContext
Remove all the explicit @mut-fields from CrateContext, though many
fields are still @-ptrs.
This required changing every single function call that explicitly
took a @CrateContext, so I took advantage and changed as many as I
could get away with to &-ptrs or &mut ptrs.

efc71a8bdb std: unify the str -> [u8] functions as 3 methods: .as_bytes() and .as_bytes_with_null[_consume]().
The first acts on &str and is not nul-terminated, the last two act on strings
that are always null terminated (&'static str, ~str and @str).

8408012ca4 The null case of a nullable-poiner enum might not be nullary.
Cases like `Either<@int,()>` have a null case with at most one value but
a nonzero number of fields; if we misreport this, then bad things can
happen inside of, for example, pattern matching.

Closes #6117.

cad226025b librustc: implement a #[packed] attribute for structs.
A struct (inc. tuple struct) can be annotated with #[packed], so that there
is no padding between its elements, like GCC's `__attribute__((packed))`.

9eaa608b04 Get rid of the Unit enum representation.
The only thing we really lose is that C-like enums with one variant and a
non-zero discriminant now take up space, but I do not think this is a
common usage.  As previously noted, that was mostly there for
transitional compatibility with the pre-adt.rs codebase.

e6b5e00ea2 Simplify struct representation.
Out goes the extra layer of struct wrapping; the destructedness flag is
added to the end of the struct.  This means that, if the struct
previously had alignment padding at the end, the flag will live there
instead of increasing the struct size.
