Are we open already? I see PPC changes had collided with my patch. Even
if it's too early to push the patch, I merged the upstream changes into
the updated webrev:
  http://cr.openjdk.java.net/~shade/8031818/webrev.01/

Instead of introducing a new method, I rewired the predicate and
rearranged the comments to make its structure clear. I think extracting
method is not required now. Also, a few typos corrected.

Testing:
 - full cycle JPRT
