6722113: CMS: Incorrect overflow handling during precleaning of Reference lists
Summary: When we encounter marking stack overflow during precleaning of Reference \
lists, we were using the overflow list mechanism, which can cause problems on account \
of mutating the mark word of the header because of conflicts with mutator accesses \
and updates of that field. Instead we should use the usual mechanism for overflow \
handling in concurrent phases, namely dirtying of the card on which the overflowed \
object lies. Since precleaning effectively does a form of discovered list processing, \
albeit with discovery enabled, we needed to adjust some code to be correct in the \
                face of interleaved processing and discovery.

6684579: SoftReference processing can be made more efficient
Summary: For current soft-ref clearing policies, we can decide at marking time if a \
soft-reference will definitely not be cleared, postponing the decision of whether it \
will definitely be cleared to the final reference processing phase. This can be \
especially beneficial in the case of concurrent collectors where the marking is \
                usually concurrent but reference processing is usually not.
