Work around an apparent compiler bug to make my patch run

Without this, it would fail when optimization is turned on. The result of

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.
