b1bf9ef5ae Break fold's circular reference during unwinding 
This converts the AST fold into a resource that breaks it's own circular
reference (just a temporary workaround until GC), so that failure during fold
will unwind correctly.

Issue #936

eafb6789a2 Stop creating function pairs for static functions 
These are now called directly. When taking their value, a null pointer is added
to create a pair.

43b219dbec Work around an apparent compiler bug to make my patch run 
Without this, it would fail when optimization is turned on. The result of
the Load(bcx, llclosure) call would end up in llenv in a corrupted form.

575aae407b Saner approach to lvalues and callable values in trans 
LValues no longer carry information about generics and objs, instead
there's an extended form of lvalue, lval_maybe_callee, only used by
call and bind, which holds this info.

This makes it possible to take the value of a method and get a working
closure, and will (with some more work) allow us to call statically
known functions without loading from their pair.

f8a35234ad Remove autoderef for calls 
We were only using it in a single place, and there for no discernable reason
(probably as part of the bare-fn-vals-are-not-copyable plan). It seems more
surprising than useful.

d7587c1eda Change convention for specifying referenced argument 
It is now 1-based, rather than 0 based. (Seems more natural, and allows 0 to
be used to refer to self and maybe to closure.)

Also allows non-referenced args to be implicitly copied again.

57ede5f281 Added non_ty_var precondition to trans::type_of_inner
