Cleanups to `ParameterBlock<T>` behavior. (#304)

* Cleanups to `ParameterBlock<T>` behavior.

These add some more realistic tests using the `ParameterBlock<T>` support, and show that it can work with the "rewriter" mode.

Unfortunately, this code does *not* currently work with the rewriter + the IR at once. That will need to be fixed in a follow-on change, because I now see that the root problem is pretty ugly.

* cleanup
