Support for self-calls that take arguments.

Browse source 
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).
