Subject: [PATCH/MIPS] Add support Octeon's bbit instructions

Hi,
  Currently gdb does not support stepping over Octeon's bbit
instructions.  These instructions are branch instructions with a delay
slot but in the cop2 instruction area.

This adds the support to both mips32_next_pc and
mips32_instruction_has_delay_slot.

OK?   Built and tested on mips64-linux-gnu on an Octeon2.

Thanks,
Andrew Pinski

ChangeLog:
* mips-tdep.c (is_octeon): New function.
(isocteonbitinsn): New function.
(mips32_next_pc): Handle Octeon's bbit insturctions.
(mips32_instruction_has_delay_slot): Likewise.
