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
ASTAT, so add size checks to the ashiftrt/lshiftrt helpers.

The logical shift insn does not sign extend before shifting, so
we shouldn't either.

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.

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.

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.

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.

Some saturation cases with dsp mac insns were not setting the V flag.
So implement that part and split up the logic between the dual macs.

Our handling of the M_IU/M_TFU modes are missing signed saturation when
the MM flag is set, so add it to match the hardware behavior.

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.

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.

When the accumulator saturates, it needs to be greater than, but not
equal to, the largest unsigned value as this is what the hardware does.
