myvalue as myiface should, if myvalue is of a type that has an impl of myiface in scope, copy the value into a boxed representation, along with the dict needed to treat it as myiface. Values of such a type can have methods called on them, which will be resolved through the dict.

This depends on #1436

Add cases for iface values to rust_shape.h

They appear to log okay now, but I can't promise much beyond that.

@pcwalton If you feel like taking a look, I'd be grateful. Interfaces are
boxes containing a (tydesc, dict, value_of_any_type) tuple, where the leading
tydesc describes the whole tuple.
