21be1379d5 Rename some core::option functions 
from_maybe => get_with_default
maybe => with_option
may => with_option_do

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

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).

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);

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.

e2fa6f03f5 Translate simple classes 
Programs using classes with fields only (no methods) compile and run,
    as long as nothing refers to a class in a different crate (todo).

    Also changed the AST representation of classes to have a separate
    record for constructor info (instead of inlining the fields in the
    item_class node), and fixed up spans and pretty-printing for
    classes.
