G1DefaultMinNewGenPercent, G1DefaultMaxNewGenPercent, G1OldCSetRegionLiveThresholdPercent and G1MixedGCCountTarget are important knobs while tuning G1 and the performance team has received requests to get these available in a jdk7 update.
We would also like to make the names more user friendly e.g. - 
G1DefaultMinNewGenPercent to G1NewSizePercent,
G1DefaultMaxNewGenPercent to G1MaxNewSizePercent, 
G1OldCSetRegionLiveThresholdPercent to G1MixedGCLiveThresholdPercent
Closing as duplicate of 8001424 and 8001425. No changes will be necessary when these are fixed and backported to hsx24.

Might be handled by other CRs so no action might be needed for this CR.
