Only log incrementally deserialized maps with --trace-maps instead of
iterating the whole heap and print all existing maps on every partial
deserialization for new contexts. This should greatly improve
performance of --trace-maps on websites with many iframes.
- Add helpers to share code: LogNewObjectEvents, LogScriptEvents,
LogNewMapEvents
- Link AllocationSites before any GC
