ck_hs: Re-use tombstones near load factor.
...
This is similar to the set of changes done to ck_ht.
In addition to this, a bug was caught were minimal
probe sequence was based on last rather than first
tombstone observed.
This hashset will now face long-running bursty
write -> delete -> write workloads much more effectively
and includes significant performance improvements for
delete heavy workloads (at least 2x measured).

ck_ht: Enable aggressive re-use of tombstones.
...
Previously, a probe to an empty slot was necessary in order
to avoid hash table growth. As long as a tombstone is available,
re-use it. This prevents excessive growth on workloads involving
long bursts of writes (near 0.5 load factor) followed by long
bursts of deletes.

CK_LIST_INSERT_HEAD was incorrectly managing prev

ck_ring: Add a work-around for compiler bug(s) in ck_ring_dequeue_spmc.
...
Both LLVM-backed compilers and GCC incorrectly treat
a barrier-sandwiched load as a loop invariant in dequeue_spmc.
Forcing volatile atomic load semantics generates the right
thing.
Thanks to Devon O'Dell and Abel Mathew for help in catching
this issue.

The terminology used in ck_backoff now reflects terminology
used in literature.
ck_backoff_gb has been removed.
