arch-power: Fix branch conditional instructions

Among the register-based conditional branch instructions,
the ones using CTR should not decrement CTR when the bit
corresponding to this action is set in the BO field of
the instruction. In this case, the instruction should be
considered invalid. This fixes the following instructions.
  * Branch Conditional to Count Register (bcctr[l])
