7146246: G1: expose some of the -XX flags that drive which old regions to collect during mixed GCs Summary: Make two G1 cmd line flags available in product builds: G1HeapWastePercent (previously called: G1OldReclaimableThresholdPercent) and G1MixedGCCountTarget (previous called: G1MaxMixedGCNum). Also changed the default of the former from 1% to 5% and the default for G1OldCSetRegionLiveThresholdPercent to 90%. Reviewed-by: azeemj, jwilhelm, johnc
