Support IR-based codegen for a few more examples.

The main interesting change here is around support for lowering of calls to "subscript" operations (what a C++ programmer would think of as `operator[]`).

An important infrastructure change here was to add an explicit AST-node representation for a "static member expression" which we use whenever a member is looked up in a type as opposed to a value. The implementation of  this probably isn't robust yet, but it turns out to be important to be able to tell such cases apart.
