Extended Mnemonics for instructions in extension sets E7E0-E7EF

All instructions in this table are six bytes in length. The first byte always has a value of X'E7', the second byte of the opcode is located in the sixth byte of the instruction and always has a value in the range X'E0' through X'EF'.
