RFR: 8069367: assert(_nextMarkBitMap->isMarked((HeapWord*) obj)) failed

Here’s the new webrev:

Incremental:

I haven’t done a full Aurora performance run with this new version, but the synthetic benchmark
Thomas gave me isn’t showing any degradation.  (In fact, once again today, the new version
is running a tiny bit faster on that benchmark, e.g. the real difference is pretty much in the noise.)
