sim: bfin: fix ASTAT/correctness issues with arithmetic shifts
This improves some of the arithmetic shifts to better match the
hardware (especially wrt ASTAT behavior). We hit areas where
the published documentation is thin so we have to rely on tests
run on the hardware to figure out how things should behave.
