add a SelectionDAG method to check if no common bits are set in two nodes; NFCI
This was suggested in:
http://reviews.llvm.org/D13956
and is a follow-on to:
http://reviews.llvm.org/rL252515
http://reviews.llvm.org/rL252519

A corresponding function for IR instructions already exists in ValueTracking.
