Incredibly questionable virtual AHI device support
...
To test this, install AHI (probably preferably 4.18) and copy pi-ahi.audio to DEVS:AHI and PI-AHI to DEVS:AudioModes.
The IRQ trigger magically doesn't work, so this all runs of vertical blank... meaning that it stops working pretty much the instant you try to use it in an RTG mode.
Not very useful at the moment, but I need to take a break from working on this to do a bunch of work.

Get rid of Musashi separate writes
...
The separate writes functionality of Musashi was severely getting in the way of any kind of caching of bus longwords, and I found that the negatvie performance impact of disabling separate writes could be negated by creatively applying the address translation cache to the FC reads/writes instead.
This commit requires a `make clean` before rebuilding the emulator with `make`.

this way we can pass around one pointer and access them all in the future.
This happens to win 5-10% performance, because now the code generator can generate a single
global variable pointer to get to all of the translation cache/range fields at once.
