[PATCH v1 1/1] opcodes: microblaze: Add hibernate and suspend instructions

[Frager, Neal]

> This patch adds the MicroBlaze hibernate and suspend instructions.

> Further documentation of these instructions can be found here:
> https://docs.xilinx.com/v/u/en-US/ug984-vivado-microblaze-ref

> This patch also re-adds the clz, mbar, sleep, swapb and swaph instructions which were missing from the MicroBlaze instruction list for some reason.
