Philippe Mathieu-Daudé e895095c78 target/mips: Only update MVPControl.EVP bit if executed by master VPE 
According to the 'MIPS MT Application-Specific Extension' manual:

  If the VPE executing the instruction is not a Master VPE,
  with the MVP bit of the VPEConf0 register set, the EVP bit
  is unchanged by the instruction.

Modify the DVPE/EVPE opcodes to only update the MVPControl.EVP bit
if executed on a master VPE.
