ck_fifo: Add back-off and remove recycle.
...
Recycle will just be a bottleneck. The MPMC interface should instead
return a junk pointer and allow the user to manage its lifetime in
a way they see fit.

x86_64: Remove workaround for Opteron errata, other minor clean-up.
...
There is a bug first generation AMD Opteron processors'
with cpuid family 0Fh and models less than 40h when it
comes to read-modify write operations after load/store
sequence. Not worth supporting this processor.
If you are on this processor, you can find more information

ck_barrier: First round audit, tournament barriers next.
...
The barriers have been restructured into individual file
per implementation. Some micro-optimizations were implemented
for some barriers (caching common computations in the barrier).
State subsription is now explicit with the TID counter allocated
on a per-barrier basis.
Tournament barriers remaining and then another round will be done
for correctness and algorithmic improvements.
