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. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
