sim: bfin: set ASTAT AV/AVS when shifting accumulators overflow

The LSHIFT/ASHIFT insns that work with accumulators lacked AV/AVS
handling in the ASTAT register, so add it to match the hardware.

If we're shifting accumulators, we don't want to touch the V bit in

sim: bfin: handle large shift values with accumulator shift insns

When the shift magnitude exceeds 32 bits, the values rotate around (since
the hardware is actually a barrel shifter).  So handle this edge case,
update the corresponding AV bit in ASTAT which was missing previously,
and tweak the AZ setting based on how the hardware behaves.

sim: bfin: handle odd shift values with shift insns

The shift magnitude is a 5-bit signed value.  When it is between 0 and
15, then we do the requested shift, but when it is outside of that, we
have to do the opposite.

That means we flip between lshift and ashiftrt to match the hardware.

sim: bfin: fix M_IH saturation size

This reverts the previous commit and does it right.  This change got
lost in the shuffle of patches I have pending.

Basically the logic is to change the 32bit saturation (and then masked
to 16bits) to a proper 16bit saturation.

sim: bfin: fix sign extension in dsp insns with MM flag

After testing the hardware with all the different dsp flags, the MM flag
triggers sign extension in all modes.  So drop the limited use of it, and
the local custom helper that was also extending unsigned values.  We also
can see that the flag checks in the mult/mac insns have the same behavior
with sign extending, so add a helper func to keep the logic the same in
both places.
