opcodes/arc: Support dmb instruction with no operands

In this GCC commit:
  https://gcc.gnu.org/ml/gcc-patches/2015-12/msg00735.html
GCC started emitting dmb instructions with no operands.  The intention
was that dmb with no operands should be an alias for 'dmb 0'.

The following patch extends the arc opcodes library to support dmb with
no operands.

opcodes/ChangeLog:

* arc-tbl.h (dmb): Add a no operand version of dmb.
