The interpreter's MMIO dispatch was a hardcoded chain for GPIO and the syscon
serial port. Devices now register an address range in Core/HW/MMIO and get
each access with its width and the MIPSState making it, for registers that
answer each CPU differently. An access no device handles is logged and reads
as poison, as before.
GPIO and syscon serial become the first two devices. They're reset at boot,
which they never were, and saved in savestates (SaveStart section version 4).
ll/sc, lwl/lwr and lwc1/swc1 reach MMIO in the interpreter too, and kernel
blocks leave lwc1/swc1 to it like the other loads and stores. swl/swr and
lv/sv still treat it as a bad address. TestMMIO runs a kernel-mode access on
each core and the registers through a savestate.

Config.h is edited about 100 times a year and each edit recompiled 198
files; now 172. SmallDataConvert.h pulls in arm_neon.h and was included by
headers that don't use it.

These generally work, but likely delay slots will make downcount slightly
off, and won't resume when you hit run again without manually stepping
through them.
