This is a follow up patch with https://reviews.llvm.org/D70436. The custom node PPCISD::XXREVERSE was added by commit https://reviews.llvm.org/D33690, which has completely the same semantics of generic node ISD::BSWAP.  
We need to clean up it as we have the combine rules for bswap in the base class, while nothing for xxreverse.
