#8014320 would benefit from #5100935

Posting to the list because I can't add comments on
http://bugs.openjdk.java.net.

I just wanted to point out that if #5100935 were implemented, it would
allow for a speed improvement of an estimated 20% for SS multiplication
in the 20,000 - 80,000 digit range.

There are other improvements to 8014320 that could be done now, but they
would only make a difference well into the 100,000s of digits.
