064f82d68d Support returning from loop blocks
The code is somewhat invasive, but it seems hard to do this in a
clean way, since the design itself involves a bunch of 'action
at a distance'.

Issue #1819

f6e3738b9c Support an alternate for syntax that calls a higher-order function
The last argument of the call must be a block, and the type of this
argument must a function returning bool. `break` and `cont` are
supported in the body of the block, and return `false` or `true` from
the function. When the end of the function is reached, `true` is
implicitly returned.

    for vec::all([1, 2, 3]) {|elt|
        if elt == 2 { break; }
        log(error, elt);
    }

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.

8bbd78075f Handle self correctly when translating classes
This change uses the same code for handling the "self" reference for
classes as is already used for impls/ifaces. This allows removing the
extra maybe_self_id argument (which was just for classes) to trans_closure
that I added before. I also rewrote the translation for class ctors so
that it doesn't generate new AST nodes (instead translating directly).

Also changed visit so that it visits class ctors correctly with visit_fn,
and changed typestate to not do return-checking when visiting a class ctor.
