Extended mnemonics changes

The extended mnemonics for POWER® family and PowerPC®.

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