ef26d60eba 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.

26bb3ddd50 gas/opcodes: blackfin: move dsp mac func defines to common header
The mmod field is decoded in a few places (gas/opcodes/sim), so move it to
a common place to avoid duplication.

73a63ccf2f opcodes/gas: blackfin: support OUTC debug insn
The disassembler has partial (but incomplete/broken) support already for
the pseudo debug insn OUTC, so let's fix it up and finish it.  And now
that the disassembler can handle it, make sure our assembler can output
it too.
