Changed the expansion of new space to depend on how much has survived scavenge.
This replaces the fixed expansion policy based on number of scavenges.
Increased the max new space size to 8MB (only reserved space).
Increased the defalt new space size to 512KB.

survivived -> survived

Line 742: PromotedSpaceSize() + new_space_.Size() - survived_watermark;
Maybe reorder these to make it (crystal) clear that you're adding
new_space_.Size() and the promoted space growth to the last expansion variable.
