Adds a very basic shadowing test.
...
For the record, I'm aware that there's a lot here that I'm not testing. I think the smart move is to get towards a running machine and see which configurations it actually tries to set up, then follow along with appropriate testing; it might cause me to discover a flaw in my comprehension before I've made the same mistake in both the code and a test.

Still to do: card paging, and finding out which banks that applies to, and shadowing. So: everything with flags.

This allows me to fix the final two implicit conversion warnings, albeit that it would have been nice to find a templatey way just to get the type directly from the declaration of `perform_bus_operation`.

Ensures intended 65816 exception behaviour.
...
i.e. the relevant micro-op sequence exists, and its operation isn't lost. Also sets the 65816 by default to jump straight into power-on, not to execute an instruction first. That shouldn't make a functional difference, but it makes debugging easier because it makes startup fully deterministic.
