6814437: G1: remove the _new_refs array
Summary: The per-worker _new_refs array is used to hold references that point into \
the collection set. It is populated during RSet updating and subsequently processed. \
In the event of an evacuation failure it processed again to recreate the RSets of \
regions in the collection set. Remove the per-worker _new_refs array by processing \
the references directly. Use a DirtyCardQueue to hold the cards containing the \
references so that the RSets of regions in the collection set can be recreated when \
                handling an evacuation failure.

collection set is empty, we would still try to do a pause even if it is to update the \
RSets and scan the roots). This changeset removes the code and structures associated \
                with abandoned pauses.

6930581: G1: assert(ParallelGCThreads > 1 || n_yielded() == _hrrs->occupied(),"Should \
                have yielded all the ..
Summary: During RSet updating, when ParallelGCThreads is zero, references that point \
into the collection set are added directly the referenced region's RSet. This can \
cause the sparse table in the RSet to expand. RSet scanning and the "occupied" \
routine will then operate on different instances of the sparse table causing the \
assert to trip. This may also cause some cards added post expansion to be missed \
during RSet scanning. When ParallelGCThreads is non-zero such references are recorded \
on the "references to be scanned" queue and the card containing the reference is \
recorded in a dirty card queue for use in the event of an evacuation failure. Employ \
the parallel code in the serial case to avoid expanding the RSets of regions in the \
                collection set.

6948538: CMS: BOT walkers can fall into object allocation and initialization cracks
Summary: GC workers now recognize an intermediate transient state of blocks which are \
allocated but have not yet completed initialization. blk_start() calls do not attempt \
to determine the size of a block in the transient state, rather waiting for the block \
to become initialized so that it is safe to query its size. Audited and ensured the \
order of initialization of object fields (klass, free bit and size) to respect block \
state transition protocol. Also included some new assertion checking code enabled in \
                debug mode.
