The single cycle dual mac ABS insn was incorrectly decoding the mac1
part of the insn.
Once we fix the decode, update the gas tests to have the correct output.
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
When assigning to a register half, the mac0 part of the mult insn
was not decoding properly. It would always show a full dreg instead
of the dreg low half.
Once we fix the disassembler, we have to update a few of the gas
tests as their previous expected output was incorrect.
