This change allows one to assemble (and disassemble) PPC32 external pid instructions specific to e500mc CPUs.
The list and details are available in https://www.nxp.com/docs/en/reference-manual/E500MCRM.pdf (3.4.11.2).
The encoding is defined in http://cache.freescale.com/files/32bit/doc/ref_manual/EREF_RM.pdf (6.4).

This was additionally tested against gcc except dcbzlep instruction which gcc does not support.
