This method must return a valid register class, or the list-ilp isel scheduler will crash. For MVT::Untyped nullptr was previously returned, but now ADDR128BitRegClass is returned instead. This is needed just as long as list-ilp (and probably also list-hybrid) is still there. Review: Ulrich Weigand, A Trick https://reviews.llvm.org/D32802 llvm-svn: 302649
