rev 3905 : 8001424: G1: Rename certain G1-specific flags
Summary: Rename G1DefaultMinNewGenPercent, G1DefaultMaxNewGenPercent, and G1OldCSetRegionLiveThresholdPercent to G1NewSizePercent, G1MaxNewSizePercent, and G1MixedGCLiveThresholdPercent respectively. Continue, however, to accept the previous names. If both are specified, the new name takes precedence.
