Track the callee expression in full, instead of only tracking the callee's FunctionId. This results in the `name_reference` denoting the function actually being used. Lowering now propagates a `llvm::Function*` as the value associated with expressions of type `<function>`. We were not creating `NameReference` node for names produced by member access into a namespace, such as the second name in `Namespace.Function`, which caused lowering of calls to such names to fail. This is now fixed, but the resulting `NameReference` node only refers to the name and the lookup result, not to the `Namespace.` qualifier. We'll need to decide how to fit a third operand into that node (perhaps we can stop storing the `name_id`, since it can be derived from the lookup result) but for now the qualifier is not tracked.
