Extended Mnemonics Changes

The following lists show the added extended mnemonics for POWER and PowerPC. The assembler places all POWER and PowerPC extended mnemonics in the POWER/PowerPC intersection area if their basic mnemonics are in this area. Extended mnemonics are separated for POWER and PowerPC only for migration purposes. See "Extended Instruction Mnemonics Overview" for more information.
