  1. Add more performant in-reg byte-reverse series of instr for P8 & P9 

    As rlwimi became cheaper in P8 & P9, using it for in-register
byte-reverse instruction sequence results in less total instructions
and better performance

  2. Wrap instr mask constant into CONSTANT64() in Power byteSwap 

    This to ensure same constant and argument type-length
in 64- and 32-bit run modes.
