Erik, Andreas, please take a look.
My strategy here is:
1. Only test scenarios that we care about (for super lookups, only method calls
and calls to named getters and setters)
2. These are microbenchmarks - some care is taken to prevent dead code
elimination etc.

Michael, please take a look to make sure I've got all the infrastructure stuff
right.

Object.setPrototypeOf(Derived, Base)

too? Since that makes these look more like classes.
