sim: bfin: tweak saturation handling with TFU/FU modes and MM bit
This too should have been squashed into an earlier change. It covers
a few more cases in the V/VS saturation patch when working with TFU
and FU modes of dsp insns.

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 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.

sim: bfin: fix dsp insns IH saturation/rounding behavior
When using the IH modifier, we need to first saturate the value before
rounding it, and then further saturate it a bit more. This makes the
sim match the hardware behavior with these insns.
