1092bbfff0 Support for self-calls that take arguments. 
Nicer parsing of self-calls (expr_self_method nodes inside expr_call
nodes, rather than a separate expr_call_self) makes typechecking
tractable.  We can now write self-calls that take arguments and return
values (see: test/run-pass/obj-self-*.rs).

2e90bd94de Continued sketching out code for checking states against preconditions. 
It's still sketchy. I added a typestate annotation field to statements
tagged stmt_decl or stmt_expr, because a stmt_decl statement has a typestate
that's different from that of its child node. This necessitated trivial
changes to a bunch of other files all over to the compiler. I also added a
few small standard library functions, some of which I didn't actually end
up using but which I thought might be useful anyway.

4fc8de1969 Last pieces of self-call support. 
The last few pieces of the hack that lets us use trans.trans_call() to
translate self-calls, plus a fix for the parser buy that was
preventing self-call expressions from getting past parsing.
test/run-pass/obj-self.rs works now (as in it actually prints "hi!"
twice!).

3130348ee1 Started adding support for typestate checking. 
I added a new field to the ast "ann" type for typestate information.
Currently, the field contains a record of a precondition bit vector and
postcondition vector, but I tried to structure things so as to make
it easy to change the representation of the typestate annotation type.
I also had to add annotations to some syntactic forms that didn't have
them before (fail, ret, be...), with all the boilerplate changes
that that would imply.

The main call to the typestate_check entry point is commented out and
the actual pre-postcondition algorithm only has a few cases
implemented, though the overall AST traversal is there. The rest of
the typestate algorithm isn't implemented yet.
