[PATCH] Add support for MIPS R6 evp and dvp instructions.


Hi,

This patch adds support for the MIPS R6 enable/disable virtual processor 
instructions (evp/dvp).  The documentation for the instructions is available at 
http://www.imgtec.com/mips/architectures/mips32.asp 

The patch and ChangeLog is below.

Ok to commit?

Many thanks,


Andrew
