802519ea53 7127706: G1: re-enable survivors during the initial-mark pause
Re-enable survivors during the initial-mark pause. Afterwards, the concurrent marking threads have to scan them and mark everything reachable from them. The next GC will have to wait for the survivors to be scanned.

0fa6fc2279 6484965: G1: piggy-back liveness accounting phase on marking
Remove the separate counting phase of concurrent marking by tracking the amount of marked bytes and the cards spanned by marked objects in marking task/worker thread local data structures, which are updated as individual objects are marked.

1d3b26e52b 6888336: G1: avoid explicitly marking and pushing objects in survivor spaces
This change simplifies the interaction between GC and concurrent marking. By disabling survivor spaces during the initial-mark pause we don't need to propagate marks of objects we copy during each GC (since we never need to copy an explicitly marked object).
