The CL does a few things:
* Rename "forwarder" to "dispatcher" to disambiguate them from actual
dynamic forwarders:
- "dynamic dispatcher": A function that takes all arguments of a
dynamic call & dispatches them to the right target (which is a
dynamic forwarder).
- "dynamic forwarder": A function that takes arguments, type checks
them, unboxes them (if applicable), calls the real function, boxes
the result (if applicable).
* Make dynamic setter dispatchers & forwarders have `void` return type.
Setters in Dart don't produce values, the call sites turn `a.b = c`
into something like this: `let tmp = c in (let a.b=(tmp) in tmp)`
* Make `CallShape` remember not just the argument shape but also whether
it was a getter, setter or method.
