Review request for JDK-8011095 PropertyHashMap.rehash() does not grow enough

[Hannes Wallnoefer]

Looks good to me. The one thing I'm not sure about is the implications 
of not caching history for empty properties. On the one hand it seems 
plausible to avoid creating a huge property map tree where nothing is 
ever garbage collected, but on the hand everything starting at the empty 
properties map will not use history while still recording it, which is a 
wasted effort.

I think we should do some testing with octane to see what operations 
actually use history or not with this scheme.
