We weren't updating AZ when doing a 16bit add or sub insn. Implement it.

No point in moving unchanged acc values to the acc regs, and avoid
updating the acc ASTAT bits when only reading. This fixes incorrect
changing of the ASTAT bits when they're only being read.

The current dsp mult handler does not take care of overflows which turn
values negative (and thus set AN in ASTAT). So implement it.

When testing ASTAT regs, specific bit differences carry a lot more meaning
than when checking the value of a data register. So automatically decode
the bits of the two values and print things out so that people don't have
to manually do it themselves every time.

This can boot Das U-Boot and a Linux kernel. It also supports Linux
userspace FLAT and FDPIC (dynamic and static) ELFs.
