Description
During the review of JDK-8159422 we found that the G1CMMarkStack::_out_of_memory member may be redundant, just mirroring the value of G1ConcurrentMark::_has_overflown.

Verify that this is the case and if so, remove it, and replace its uses by has_overflown.
Comments
Or make G1ConcurrentMark::has_overflown forward to G1CMMarkStack::is_out_of_memory.
