Philip Reames 8b5b294ec2 [SCEV] Print predicate backedge count only if new information available 
When printing the result of SCEV's analysis, we can avoid printing
the predicated backedge taken count and the predicates if the predicates
are empty and no new information is provided.  This helps to reduce the
verbosity of the output.
